  More info

  To avoid excluding individuals with limited English proficiency from participating in research, the consent form and other documents should be presented to them in their primary language and in a format that is understandable. However, evidence suggests that, when documents are translated for prospective and actual research participants with limited English proficiency, these individuals often fail to engage with the documents and the research in the same terms as their English-speaking counterparts do. We argue that this is because methodological challenges remain after a decision to translate has been made. This study investigated how translation approaches affected reader response and intelligibility. Participants were asked to review two translated versions of a survey (which reflected a functionalist and a literal approach to translation) followed by semistructured interviews. Quantitative and qualitative analysis revealed a preference for a functionalist translation and a higher number of problems raised in regard to the literal translation. The recommendations we offer here include considering the most appropriate translation approach for a specific genre and purpose.

  More info

  Adults with hearing loss report a wide range of hearing aid satisfaction that does not significantly correlate to degree of hearing loss. It is not clear which auditory behavioral factors do contribute to hearing aid satisfaction. While poor speech understanding in noise is known to contribute to dissatisfaction, there are many categories of this type of assessment. The purpose of this systematic review is to answer the question, "Are behavioral pre-fitting measures using speech and nonspeech materials related to hearing aid satisfaction among adults?"

  Purpose The aim of this tutorial is to share lessons learned from a speech, language, and hearing sciences department at a land-grant, Hispanic-serving institution (HSI) after revising the graduate admissions review process and subsequent discussions related to equity in assessment. This tutorial describes the department as a case example and includes guiding questions that may be helpful for other organizations. Method An adaptive case study approach was used and centered on supporting students at Hispanic-serving institutions. The approach was characterized by structured collaborative reflection throughout the process and engagement of relevant stakeholders at multiple levels. The adaptive method allowed for interim synthesis of stakeholder discussions to inform subsequent phases of the reflection process. Results This tutorial shares critical motivations, barriers, facilitators, and phases that were identified in moving toward holistic evaluation for graduate admissions. Targeted areas for continued improvement related to diversity, equity, and inclusion are described. Conclusions This tutorial outlines lessons learned from changing graduate admissions practices toward holistic review. Self-reflection prompts are provided for institutions and organizations considering changes to their review process. In order to best support diverse communities, increased workforce diversity is needed in the speech, language, and hearing sciences professions, and holistic review practices are recommended as one way to support increased diversity, equity, and inclusion.

  Purpose Teleaudiology helps improve access to hearing health care by overcoming the geographic gap between providers and patients. In many teleaudiology encounters, a facilitator is needed at the patient site to help with hands-on aspects of procedures. The aim of this study was to review the scope and nature of research around patient-site facilitators in teleaudiology. We focused on identifying the facilitators' background, training, and responsibilities. Method To conduct this scoping review, we searched PubMed, CINAHL, and Embase. To be included, studies needed to address teleaudiology; be experimental/quasi-experimental, correlational/predictive, or descriptive; be published in English; and include the use of a facilitator at the patient location. Results A total of 82 studies met the inclusion criteria. The available literature described a number of different individuals in the role of the patient-site facilitator, including audiologists, students, and local aides. Fifty-seven unique tasks were identified, including orienting the client to the space, assisting with technology, and assisting with audiology procedures. The largest number of studies ( = 42) did not describe the facilitators' training. When reported, the facilitators' training was heterogenous in terms of who delivered the training, the length of the training, and the training content. Conclusions Across studies, the range of duties performed by patient-site facilitators indicates they may have an important role in teleaudiology. However, details are still needed surrounding their background, responsibilities, and training. Future research is warranted exploring the role of the patient-site facilitator, including their impact on teleaudiology service delivery.

  Purpose The purpose of this study is to determine the sensitivities and specificities of different audiometric hearing screening criteria and single-item and multi-item hearing disability questionnaires among a group of Spanish-speaking adults in a rural community. Method Participants were 131 predominantly older (77% 65+ years) Hispanic/Latinx adults (98%). A structured Spanish-language interview and pure-tone threshold test data were analyzed for each participant. The sensitivities and specificities of three single questions and the Hearing Handicap Index for the Elderly-Screening (HHIE-S; Ventry & Weinstein, 1983) in Spanish, as well as three audiometric screening criteria, were evaluated in relation to the pure-tone threshold test for detecting hearing loss. Results Sensitivity and specificity of audiometric screening criteria varied, but the highest sensitivity was found for the criterion of > 25 dB HL at 1-4 kHz in either ear. The single self-perception question, " ( was shown to be the most sensitive self-report screening compared to other single-item questions and the HHIE-S. This single question was as sensitive as an audiometric screening to detect a moderate hearing loss (> 40 dB HL in either ear). Results from the Spanish HHIE-S indicated poor performance to detect hearing loss in this population, consistent with previous research. Conclusions Among older Spanish-speaking adults, self-reported hearing status had varying sensitivities depending on the question asked. However, of the tools evaluated, the self-perception question proved to be a more sensitive and specific tool than a multi-item screen. Objective audiometric testing (> 25 dB HL) resulted in the highest sensitivity to detect a mild hearing loss.

  Aural Rehabilitation (AR) aims to minimise negative effects of hearing loss. However, there has been limited study of the lived experience of clients receiving Aural Rehabilitation services, particularly for disparity populations. The purpose of this study is to demonstrate the use of an innovative qualitative approach to investigating communication in an AR setting among Hispanic/Latino older adult dyads. We developed a qualitative phenomenology approach using observation methods to document and analyse how individuals experience living with acquired hearing loss within group AR. Trained observers collected systematic, detailed notes on observations of participants over the course of a 5-week community-based AR intervention. In partnership with audiologists, Community Health Workers facilitated the intervention, which focussed on decreasing negative communication impacts of hearing loss for families. Audiometric data and subjective hearing disability results, using the HHIE-S Spanish version, are presented as additional context for observation outcomes. Participants were older Hispanic/Latino adults with hearing loss and their frequent communication partners (five dyads). Four themes related to the experience of communication emerged among dyads in the intervention: (i) emotions related to hearing loss (ii) communication dynamics, (iii) self-management of hearing loss, and (iv) hearing health advocacy. A mixed methods approach that includes group observation would contribute substantially to comprehensively evaluating group AR interventions.

  Untreated hearing loss is recognized as a growing global health priority because of its prevalence and harmful effects on health and well-being. Until recently, little progress had been made in expanding hearing care beyond traditional clinic-based models to incorporate public health approaches that increase accessibility to and affordability of hearing care. As demonstrated in numerous countries and for many health conditions, sharing health-care tasks with community health workers (CHWs) offers advantages as a complementary approach to expand health-service delivery and improve public health. This paper explores the possibilities of task shifting to provide hearing care across the life course by reviewing several ongoing projects in a variety of settings - Bangladesh, India, South Africa and the United States of America. The selected programmes train CHWs to provide a range of hearing-care services, from childhood hearing screening to management of age-related hearing loss. We discuss lessons learnt from these examples to inform best practices for task shifting within community-delivered hearing care. Preliminary evidence supports the feasibility, acceptability and effectiveness of hearing care delivered by CHWs in these varied settings. To make further progress, community-delivered hearing care must build on established models of CHWs and ensure adequate training and supervision, delineation of the scope of practice, supportive local and national legislation, incorporation of appropriate technology and analysis of programme costs and cost-effectiveness. In view of the growing evidence, community-delivered hearing care may now be a way forward to improve hearing health equity.

  Epidemiologic studies reveal disparities in hearing health care with lower prevalence of hearing aid use among older adults from racial/ethnic minority groups and lower socioeconomic positions. Recent national reports recommend exploring innovative delivery models to increase the accessibility and affordability of hearing health care, particularly for underserved and vulnerable populations. With an expected rise in the prevalence of age-related hearing loss over the next four decades due to a rapidly aging population, the condition is a growing public health imperative. This review describes key public health practices for developing and delivering community-based care that characterizes an emerging area of research in novel approaches of hearing loss management programs to reach underserved populations. With evolving technologies that enable care to extend beyond the clinic, adapting a long-utilized community health worker approach presents a strategy for the field of hearing health care to be actively involved in designing and leading initiatives for achieving hearing health equity. Principles from community-based participatory research offer a paradigm for the field to integrate into its research endeavors for addressing disparities. An interdisciplinary approach for engaging these challenges offers hearing health care researchers and providers an opportunity to advance the field and delivery of care.

  Teleaudiology helps connect patients in rural and underresourced areas to hearing health care providers, minimizing the barrier of geography (Swanepoel et al., 2010). In the United States, teleaudiology is at the initial stages of implementation (Bush, Thompson, Irungu, & Ayugi, 2016). Telehealth researchers recommend conducting a comprehensive planning assessment to optimize implementation and adoption (AlDossary, Martin-Khan, Bradford, Armfield, & Smith, 2017; Alverson et al., 2008; Krupinski, 2015). A geographic analysis of the hearing aid dispensing workforce served as the initial stage of a teleaudiology planning assessment in Arizona.

  More info

  As international research studies become more commonplace, the importance of developing multilingual research instruments continues to increase and with it that of translated materials. It is therefore not unexpected that assessing the quality of translated materials (e.g., research instruments, questionnaires, etc.) has become essential to cross-cultural research, given that the reliability and validity of the research findings crucially depend on the translated instruments. In some fields (e.g., public health and medicine), the quality of translated instruments can also impact the effectiveness and success of interventions and public campaigns. Back-translation (BT) is a commonly used quality assessment tool in cross-cultural research. This quality assurance technique consists of (a) translation (target text [TT1]) of the source text (ST), (b) translation (TT2) of TT1 back into the source language, and (c) comparison of TT2 with ST to make sure there are no discrepancies. The accuracy of the BT with respect to the source is supposed to reflect equivalence/accuracy of the TT. This article shows how the use of BT as a translation quality assessment method can have a detrimental effect on a research study and proposes alternatives to BT. One alternative is illustrated on the basis of the translation and quality assessment methods used in a research study on hearing loss carried out in a border community in the southwest of the United States.

  Interventional audiology, specifically community-based outreach, can connect people with the hearing health care system. Community-based participatory research methods were applied in two phases of research to: (1) investigate the needs of families affected by hearing loss in a rural Arizona community on the U.S.-Mexico border; and (2) evaluate an outreach program on hearing health. The needs assessment included interviews with persons with hearing loss and focus groups with family members and the greater community. The needs assessment revealed that despite perceived severity of hearing loss, help-seeking for audiologic care was limited due to barriers, stigma, and low self-efficacy. Results informed development of a community-based pilot study conducted as part of an academic-community partnership between audiology, public health, and community health workers of a federally qualified health center. An outreach program, Oyendo Bien (hearing wellness), a 5-week, Spanish-language health education program for older adults (n = 21) incorporated communication strategies and behavioral change techniques. Postprogram focus groups revealed increased self-efficacy and decreased stigma. After 1 year, 7 of 9 participants with hearing loss contacted for follow-up had sought some form of hearing-related health care. Future research should further investigate interventional audiology approaches to address health disparities.

  The purpose of this laboratory-based study was to compare the efficacy of two hearing aid fittings with and without nonlinear frequency compression, implemented within commercially available hearing aids. Previous research regarding the utility of nonlinear frequency compression has revealed conflicting results for speech recognition, marked by high individual variability. Individual differences in auditory function and cognitive abilities, specifically hearing loss slope and working memory, may contribute to aided performance. The first aim of the study was to determine the effect of nonlinear frequency compression on aided speech recognition in noise and listening effort using a dual-task test paradigm. The hypothesis, based on the Ease of Language Understanding model, was that nonlinear frequency compression would improve speech recognition in noise and decrease listening effort. The second aim of the study was to determine if listener variables of hearing loss slope, working memory capacity, and age would predict performance with nonlinear frequency compression.

  Age-related hearing loss negatively affects health outcomes, yet disparities in hearing care, such as hearing aid use, exist based on race/ethnicity and socioeconomic position. Recent national efforts highlight reduction of hearing care disparities as a public health imperative. This study a) describes a community engagement approach to addressing disparities, b) reports preliminary outcomes of a novel intervention, and c) discusses implementation processes and potential for wide-scale testing and use..This was a prospective, randomized control pilot, with a 3-month delayed treatment group as a waitlist control, that assessed feasibility, acceptability, and preliminary efficacy of a community-delivered, affordable, and accessible intervention for older adults with hearing loss. Outcomes were assessed at 3 months, comparing immediate and delayed groups, and pooled to compare the cohort's pre- and 3-month post-intervention results..All participants completed the study (n = 15). The program was highly acceptable: 93% benefited, 100% would recommend the program, and 67% wanted to serve as future program trainers. At 3 months, the treated group (n = 8) experienced fewer social and emotional effects of hearing loss and fewer depressive symptoms as compared to the delayed treatment group (n = 7). Pooling 3-month post-intervention scores (n = 15), participants reported fewer negative hearing-related effects (effect size = -0.96) and reduced depressive symptoms (effect size = -0.43)..The HEARS (Hearing Equality through Accessible Research & Solutions) intervention is feasible, acceptable, low risk, and demonstrates preliminary efficacy. HEARS offers a novel, low-cost, and readily scalable solution to reduce hearing care disparities and highlights how a community-engaged approach to intervention development can address disparities.

  Hearing impairment is highly prevalent, but little is known about hearing health care among older minority adults..We analyzed nationally representative, cross-sectional data from 1,544 older adults ≥ 70 years with audiometry and hearing care data from the 2005-2006 and 2009-2010 National Health and Nutritional Examination Surveys..After adjusting for age and speech frequency pure tone average, Blacks (odds ratio [OR] = 1.68, vs. Whites) and those with greater education (OR = 1.63, ≥ college vs. < high school) were more likely to report recent hearing testing, while White older adults and those with greater socioeconomic status were more likely to report regular hearing aid use (all ps < .05). Based on a multivariate analysis, Blacks were not more likely than Whites to use hearing aids despite being more likely to have had recent hearing testing..Racial/ethnic and socioeconomic disparities exist in hearing health care and represent critical areas for research and intervention.

  Hearing loss is the third most prevalent chronic condition faced by older adults and has been linked to difficulties in speech perception, activities of daily living, and social interaction. Recent studies have suggested a correlation between severity of hearing loss and an individual's cognitive function; however, a causative link has yet to be established. One intervention option for management of the most severe to profound hearing loss in older adults is cochlear implantation. We performed a review to determine the status of the literature on the potential influence of cochlear implantation on cognition in the older adult population.

  Language acquisition typically involves periods when the learner speaks and listens to the new language, and others when the learner is exposed to the language without consciously speaking or listening to it. Adaptation to variants of a native language occurs under similar conditions. Here, speech learning by adults was assessed following a training regimen that mimicked this common situation of language immersion without continuous active language processing. Experiment 1 focused on the acquisition of a novel phonetic category along the voice-onset-time continuum, while Experiment 2 focused on adaptation to foreign-accented speech. The critical training regimens of each experiment involved alternation between periods of practice with the task of phonetic classification (Experiment 1) or sentence recognition (Experiment 2) and periods of stimulus exposure without practice. These practice and exposure periods yielded little to no improvement separately, but alternation between them generated as much or more improvement as did practicing during every period. Practice appears to serve as a catalyst that enables stimulus exposures encountered both during and outside of the practice periods to contribute to quite distinct cases of speech learning. It follows that practice-plus-exposure combinations may tap a general learning mechanism that facilitates language acquisition and speech processing.

  PMID: 22501083;PMCID: PMC3339507;Abstract: This study tested the hypothesis that the reduction in spatial release from masking (SRM) resulting from sensorineural hearing loss in competing speech mixtures is influenced by the characteristics of the interfering speech. A frontal speech target was presented simultaneously with two intelligible or two time-reversed (unintelligible) speech maskers that were either colocated with the target or were symmetrically separated from the target in the horizontal plane. The difference in SRM between listeners with hearing impairment and listeners with normal hearing was substantially larger for the forward maskers (deficit of 5.8 dB) than for the reversed maskers (deficit of 1.6 dB). This was driven by the fact that all listeners, regardless of hearing abilities, performed similarly (and poorly) in the colocated condition with intelligible maskers. The same conditions were then tested in listeners with normal hearing using headphone stimuli that were degraded by noise vocoding. Reducing the number of available spectral channels systematically reduced the measured SRM, and again, more so for forward (reduction of 3.8 dB) than for reversed speech maskers (reduction of 1.8 dB). The results suggest that non-spatial factors can strongly influence both the magnitude of SRM and the apparent deficit in SRM for listeners with impaired hearing.

  The frequency-gain curve (FGC) is among the most important parameters to consider when fitting a hearing aid. In practice, a prescriptive FGC, derived from the audiogram, is initially applied. In the subsequent fine-tuning stage, the patient often communicates their concerns about the sound quality using descriptors (e.g., "it sounds hollow") and the clinician modifies the FGC accordingly. In this study, we present and evaluate a method that could enhance this process by rapidly mapping descriptors to FGC shapes. In addition, we begin to use this method to examine the extent to which there is across-individual agreement in how descriptors map to FGC shapes.

Design: Ten listeners with hearing loss rated the extent to which each of a series of FGCs captured the meaning of a particular descriptor. Regression analyses were conducted to determine the degree to which these ratings were correlated with the gain values associated with each of 25 frequency bands. The array of slopes of these regression lines across frequency bands is termed the weighting function and was interpreted as the FGC shape that corresponded to the descriptor. We used this procedure to determine the FGC shapes associated with four of the most common descriptors used to describe hearing aid sound quality problems ("tinny," "sharp," "hollow," and "in a barrel, tunnel, or well"). Results: The weighting function shape was highly replicable despite variable listener responses, reached asymptotic performance quickly (

The focus was on the role of interaural time differences (ITDs) and time-varying interaural level differences (ILDs) under conditions varying in the strength of informational masking (IM). In the first experiment, a target talker was masked by two other talkers that were either colocated with the target or were symmetrically spatially separated from the target with the stimuli presented through loudspeakers. The sounds were filtered into different frequency regions to restrict the available interaural cues. The largest SRM occurred for the broadband condition followed by a low-pass condition.

The listeners identified the speech of a target talker masked by one or two other talkers or noises when the maskers were colocated with the target or were perceptually separated by ITDs. The results revealed a complex pattern of masking in which the factors affecting performance in colocated and spatially separated conditions are to a large degree independent.

  Previously, Marrone et al. [J. Acoust. Soc. Am. (2008)] compared spatial release from masking (SRM) for a three‐talker mixture of similar sentences in normal‐hearing (NH) listeners and listeners with sensorineural hearing loss (HL). The HL group showed significantly less SRM. In an earlier study [Marrone et al., J. Acoust. Soc. Am. (2008)] the NH group showed less SRM when the masker sentences were time‐reversed while in the colocated case a large “reversed‐masker release” (RMR) was also found. To investigate these findings, some listeners from the HL group were tested in the reversed‐masker conditions. The difference in SRM between listener groups was much smaller for reversed speech. However, the HL group also had much less RMR. Both the overall target‐to‐masker ratios (TMRs) at which comparisons are made and the spectral smearing associated with sensorineural hearing loss were likely factors, perhaps affecting amounts of energetic and informational masking. We explored these factors in a new group of N...

Instead, it requires considerable practice performing a perceptual task with relevant stimuli. It is thought that task performance permits the stimuli to drive learning. A corresponding assumption is that the same stimuli do not contribute to improvement when encountered separately from relevant task performance because of the absence of this permissive signal. However, these ideas are based on only two types of studies, in which the task was either always performed or not performed at all. Here we demonstrate enhanced perceptual learning on an auditory frequency-discrimination task in human listeners when practice on that target task was combined with additional stimulation.

The additional exposures were only beneficial when they shared the same frequency with, though they did not need to be identical to, those used during target-task performance. Their effectiveness also was diminished when they were presented 15 min after practice on the target task and was eliminated when that separation was increased to 4 h.

  While approaches that modify the frequency response of a hearing aid based on a listener’s subjective preference have demonstrated some success, they also have several limitations. Namely, these approaches (1) consider a small set of potential frequency‐gain curves (FGCs) and (2) they converge on the final FGC, which makes the outcome dependent upon the starting point. Here we present a new approach that addresses these problems by (1) considering a much larger initial set of FGCs, and (2) using a method that is not convergence based. First, the listener rates the clarity of short samples of speech filtered by a set of maximally different probe FGCs. A weighting function is then computed, where the weight given to each ∼1/3 octave frequency band is proportional to the normalized slope of the regression line between the listener’s rating and the within‐band gain of the probe FGC. Next, the listener rates the clarity of speech samples filtered by the weighting function, which is multiplied by one of several...

  Adults can learn to hear the phonetic distinctions of another language with practice. It is commonly assumed that such improvements require active performance of the target task throughout training. However, we have seen that, for other perceptual tasks, similar performance gains can be achieved by replacing some active‐performance trials with passive stimulus exposures. Here we examined the learning of a non‐native phonetic contrast using several training protocols that varied in the proportion of active and passive trials during the practice period. Native, monolingual English speakers were trained to identify a Thai phonetic contrast along a voice‐onset‐time continuum. A group given half active training and half passive exposures showed as much improvement in the category boundary as a group given active training for the entire practice period. The active‐passive group out‐performed a group given half active training and half training on an unrelated task with no passive exposures. Finally, a group giv...

Listeners selectively attended a known spatial location in two room conditions (low/high reverberation) and identified target speech in the presence of two competing talkers that were either colocated or symmetrically spatially separated from the target. The amount of spatial release from masking (SRM) with bilateral aids was similar to that when listening unaided at or near an equivalent sensation level and was negatively correlated with the amount of hearing loss.

The target talker was presented at 0° azimuth and the maskers were either colocated or symmetrically positioned around the target, with a different masker talker on each side. The symmetric placement greatly reduced any "better ear" listening advantage. When the maskers were separated from the target by ±15°, the average spatial release from masking was 8 dB. Wider separations increased the release to more than 12 dB.

Increasing reverberation in the room increased the target-to-masker ratio (TM) for the separated, but not colocated, conditions reducing the release from masking, although a significant advantage of spatial separation remained. Time reversing the masker speech improved performance in both the colocated and spatially separated cases but lowered TM the most for the colocated condition, also resulting in a reduction in the spatial release from masking.

One year later, these measures were repeated, and within category discrimination, d′, was assessed. Results: Compared with controls, implant users' vowel and sibilant labeling slopes were substantially shallower but improved over 1 year of prosthesis use. Their sensitivity to phonetic differences within phoneme categories was about half that of controls. The slopes of their goodness rating functions were shallower and did not improve. Their prototypes for the sibilant contrast (but not the vowels) were closer to one another and did not improve by moving apart. Conclusions: Implant users' phoneme labeling and within-category perceptual structure were anomalous at 1-month postimplant. After 1 year of prosthesis use, phoneme labeling categories had sharpened but within category discrimination was well below that of hearing controls. © American Speech-Language-Hearing Association.

  Although it is well documented that spatially separating speech maskers from a target speech source normally results in a release from masking, little is known about this effect in hearing aid users. The current study addressed the interaction between spatial release from masking, reverberation, age, and amplification in a multitalker soundfield experiment. The listeners had symmetric sensorineural hearing loss and were experienced users of bilateral hearing aids. The task was to identify the speech of a target talker located directly in front of the listener (0 deg azimuth) in the presence of two masker talkers co‐located with the target or spatially separated at ±90 deg azimuth. In this symmetric spatial configuration of sound sources, there was not an overall difference in target‐to‐masker ratio (T/M) at either ear during stimulus presentation, thus eliminating any ‘‘better ear’’ advantage. Reverberation was varied by physically changing the sound absorption characteristics of the sound booth in which ...

  PMID: 17552727;Abstract: This study investigates the effects of speaking condition and auditory feedback on vowel production by postlingually deafened adults. Thirteen cochlear implant users produced repetitions of nine American English vowels prior to implantation, and at one month and one year after implantation. There were three speaking conditions (clear, normal, and fast), and two feedback conditions after implantation (implant processor turned on and off). Ten normal-hearing controls were also recorded once. Vowel contrasts in the formant space (expressed in mels) were larger in the clear than in the fast condition, both for controls and for implant users at all three time samples. Implant users also produced differences in duration between clear and fast conditions that were in the range of those obtained from the controls. In agreement with prior work, the implant users had contrast values lower than did the controls. The implant users' contrasts were larger with hearing on than off and improved from one month to one year postimplant. Because the controls and implant users responded similarly to a change in speaking condition, it is inferred that auditory feedback, although demonstrably important for maintaining normative values of vowel contrasts, is not needed to maintain the distinctiveness of those contrasts in different speaking conditions. © 2007 Acoustical Society of America.

  This study examines individual differences in producing the sibilant contrast in American English and the relation of those differences to 2 speaker characteristics: (a) use of a quantal biomechanical effect (called a "saturation effect") in producing the sibilants and (b) performance on a test of sibilant discrimination. Twenty participants produced the sibilants /s/ and /S/ in normal-, clear-, and fast-speaking conditions. The degree to which the participants used a saturation effect in producing /s/ and /S/ was assessed with a custom-made sensor that measured contact of the underside of the tongue tip with the lower alveolar ridge; such contact normally occurs during the production of /s/ but not /S/. The acuteness of the participants' discrimination of the sibilant contrast was measured using the ABX paradigm and synthesized sibilants. Differences among speakers in the degree of acoustic contrast between /s/ and /S/ that they produced proved related to differences among them in their use of contact contrastively and in their discriminative performance. The most distinct sibilant productions were obtained from participants who used contact in producing /s/ but not /S/ and who had high discrimination scores. The participants who did not use contact differentially when producing the 2 sibilants and who also discriminated the synthetic sibilants less well produced the least distinct sibilant contrasts. Intermediate degrees of sibilant contrast were found with participants who used contact differentially or discriminated well. These findings are compatible with a model of speech motor planning in which goals for phonemic speech movements are in somatosensory and auditory spaces.

  In listeners with normal hearing, the sight of a speaker’s face articulating a syllable can influence the auditory percept, most observably when the auditory and visual stimuli are different from one another. This study investigates differences in audio‐visual (AV) integration (‘‘the McGurk effect’’) between adults with hearing loss who wear hearing aids (HA) and their normal‐hearing (NH) counterparts. The following hypothesis is being tested: HA users will rely more on visual input and thus be biased more toward the visual stimulus in the mismatch condition. Audio‐visual stimuli from three speakers are presented, pairing the consonants /b/, /d/, and /g/ with the vowels /a/, /i/, and /u/, in three conditions (auditory‐only, visual‐only, and AV) to the two subject groups, NH and HA. Participants label each stimulus according to the consonant perceived. Responses are coded into four categories: fusion, combination, auditory, or visual. Data analysis examines the relative strength of visual influences in the two groups. Pilot data show fusion and visual bias in an HA user. Further results will be presented. [Work supported by NIH.]

  In an earlier report, Clement et al. [J. Acoust. Soc. Am. 107, 2887 (2000)] showed that listeners’ confidence ratings of the identity of audiovisual syllables produced with conflicting auditory and visual cues were typically lower than those for audiovisually congruent syllables. This occurred even when both types of syllables were labeled consistently as the same phoneme. Confidence ratings varied across listeners, suggesting a graded nature of auditory–visual integration even across listeners who exhibit visual bias. In the current experiment, listeners were asked to identify audiovisual tokens from two talkers who elicit a high proportion of visually biased responses [Carney et al., J. Acoust. Soc. Am. 106, 2270 (1999)] and to rate their confidence in their labeling judgment. Only listeners who exhibited strong visual bias were tested in a discrimination task in which a true audiovisual /di/ was a standard. Comparison stimuli were visual /gi/‐auditory /bi/, visual /bi/‐auditory /gi/, and true audiovisual /bi/, /di/, and /gi/. Listeners were able to discriminate the visually biased and true /di/ stimuli while labeling them both as alveolar tokens. Results support the notion of a graded perception of bimodal stimuli.
