The role of tactile aids in providing information about acoustic stimuli
Journal of the Acoustical Society of America - Tập 82 Số 3 - Trang 906-916 - 1987
Devices 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 complex ...
Basic and applied research on tactile aids for deaf people: Progress and prospects
Journal of the Acoustical Society of America - Tập 75 Số 5 - Trang 1325-1342 - 1984
A 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 is discus...
Hands help hearing: Facilitatory audiotactile interaction at low sound-intensity levels
Journal of the Acoustical Society of America - Tập 115 Số 2 - Trang 830-832 - 2004
Auditory 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 the subje...
Learning a novel phonological contrast depends on interactions between individual differences and training paradigm design
Journal of the Acoustical Society of America - Tập 130 Số 1 - Trang 461-472 - 2011
Studies 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 be. The
p...
Some effects of talker variability on spoken word recognition
Journal of the Acoustical Society of America - Tập 85 Số 1 - Trang 365-378 - 1989
The 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.
In addit...
Static, dynamic, and relational properties in vowel perception
Journal of the Acoustical Society of America - Tập 85 Số 5 - Trang 2088-2113 - 1989
The 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 from the...
Acoustic characteristics of American English vowels
Journal of the Acoustical Society of America - Tập 97 Số 5 - Trang 3099-3111 - 1995
The 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 interactive
ed...
Effectiveness of spatial cues, prosody, and talker characteristics in selective attention
Journal of the Acoustical Society of America - Tập 107 Số 2 - Trang 970-977 - 2000
The 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 location ...
The role of spectral and periodicity cues in auditory stream segregation, measured using a temporal discrimination task
Journal of the Acoustical Society of America - Tập 106 Số 2 - Trang 938-945 - 1999
In 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 variability
Journal of the Acoustical Society of America - Tập 138 Số 2 - Trang 571-574 - 2015
Speech 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
benefitted ...
