Basic and applied research on tactile aids for deaf people: Progress and prospectsA brief introduction describes the alternative methods for replacement of the sense of hearing, including the educational procedures of sign language and lipreading, the medical procedure of cochlear implants, and the sensory substitution procedures of visual or tactual displays. For the tactual displays, which are most commonly electronically activated, a listing of desirable objectives i... ...

The role of tactile aids in providing information about acoustic stimuliDevices that convert sound patterns into patterns of vibrotactile stimulation have been shown in laboratory and clinical studies to enable persons to appreciate many aspects of the acoustic environment, and thus are of potential benefit to deaf persons. In the present article, a framework is outlined for describing normal listening situations as a hierarchy of tasks requiring increasingly ... ...

Hands help hearing: Facilitatory audiotactile interaction at low sound-intensity levelsAuditory and vibrotactile stimuli share similar temporal patterns. A psychophysical experiment was performed to test whether this similarity would lead into an intermodal bias in perception of sound intensity. Nine normal-hearing subjects performed a loudness-matching task of faint tones, adjusting the probe tone to sound equally loud as a reference tone. The task was performed both when t... ...

Some effects of talker variability on spoken word recognitionThe perceptual consequences of trial-to-trial changes in the voice of the talker on spoken word recognition were examined. The results from a series of experiments using perceptual identification and naming tasks demonstrated that perceptual performance decreases when the voice of the talker changes from trial to trial compared to performance when the voice on each trial remains the same. ... ...

Learning a novel phonological contrast depends on interactions between individual differences and training paradigm designStudies evaluating phonological contrast learning typically investigate either the predictiveness of specific pretraining aptitude measures or the efficacy of different instructional paradigms. However, little research considers how these factors interact—whether different students learn better from different types of instruction—and what the psychological basis for any interaction might b... ...

Static, dynamic, and relational properties in vowel perceptionThe present work reviews theories and empirical findings, including results from two new experiments, that bear on the perception of English vowels, with an emphasis on the comparison of data analytic ‘‘machine recognition’’ approaches with results from speech perception experiments. Two major sources of variability (viz., speaker differences and consonantal context effects) are addressed ... ...

Acoustic characteristics of American English vowelsThe purpose of this study was to replicate and extend the classic study of vowel acoustics by Peterson and Barney (PB) [J. Acoust. Soc. Am. 24, 175–184 (1952)]. Recordings were made of 45 men, 48 women, and 46 children producing the vowels /i,i,e,ε,æ,a,open‘‘oh’’,o,u,u,Λ,hook backward‘‘eh’’/ in h–V–d syllables. Formant contours for F1–F4 were measured from LPC spectra using a custom intera... ...

Effectiveness of spatial cues, prosody, and talker characteristics in selective attentionThe three experiments reported here compare the effectiveness of natural prosodic and vocal-tract size cues at overcoming spatial cues in selective attention. Listeners heard two simultaneous sentences and decided which of two simultaneous target words came from the attended sentence. Experiment 1 used sentences that had natural differences in pitch and in level caused by a change in the l... ...

The role of spectral and periodicity cues in auditory stream segregation, measured using a temporal discrimination taskIn a previous paper, it was shown that sequential stream segregation could be based on both spectral information and periodicity information, if listeners were encouraged to hear segregation [Vliegen and Oxenham, J. Acoust. Soc. Am. 105, 339–346 (1999)]. The present paper investigates whether segregation based on periodicity information alone also occurs when the task requires integration.... ...

Poor phonetic perceivers are affected by cognitive load when resolving talker variabilitySpeech training paradigms aim to maximise learning outcomes by manipulating external factors such as talker variability. However, not all individuals may benefit from such manipulations because subject-external factors interact with subject-internal ones (e.g., aptitude) to determine speech perception and/or learning success. In a previous tone learning study, high-aptitude individuals ben... ...
