Evaluates the effects of distorting the speech waveform envelope for suprathreshold stimuli with limited spectral information. Mixing of vowel-consonant-vowel (VCV) stimuli; Method; Subjects; Stimuli; Procedures; Results; Discussion; Details; More.
- Frequency-importance and transfer functions for recorded CID W-22 word lists. Studebaker, G.A.; Sherbecoe, R.L. // Journal of Speech & Hearing Research;Apr91, Vol. 34 Issue 2, p427
Attempts to produce frequency-importance and transfer functions for a speech recognition test so that the test could subsequently be used in studies of the proficiency factor. Uses the CID W-22; Methods; Subjects; Recording and playback procedures; Data collection procedures; Results; Conclusions.
- The establishment of open articulatory postures by deaf and hearing talkers. Tye-Murray, N. // Journal of Speech & Hearing Research;Jun91, Vol. 34 Issue 3, p453
Comments on a study which suggests that prelingually deafened talkers establish the articulatory open postures, or vowel steady states, with excessive jaw displacement and minimal tongue movement. Purpose of the investigation was to evaluate the opening gesture lingual displacement patterns of...
- A model for neurologic sources of a periodicity in vocal fold vibration. Titze, I.R. // Journal of Speech & Hearing Research;Jun91, Vol. 34 Issue 3, p460
Reports that attempts have been made in recent years to extract information about age, sex, disease, emotion, fatigue, or other physical or psychological conditions from the vocal output of a speaker. Partial success; Lack of understanding; Problem of indentifying sources; Details of the study...
- Laryngeal electromyographic activity in adductor and abductor spasmodic dysphonia. Watson, B.C.; Schaefer, S.D. // Journal of Speech & Hearing Research;Jun91, Vol. 34 Issue 3, p473
Investigates the search for distinguishing features of adductor and abductor SD to the level of neuromuscular control and analysis of intrinsic laryngeal muscle (adductor and abuductor) activity. Methods; Tasks; Data analysis; Results; Discussion; Acknowledgement; References.
- Changes in speech breathing following cochlear implant in postlingually deafened adults. Lane, H.; Perkell, J. // Journal of Speech & Hearing Research;Jun91, Vol. 34 Issue 3, p526
Examines the results of three postlingually deafened adults who received cochlear implants and then read passages before and after their prostheses were activated while their lung volumes were measured with an inductive plethysmograph that transduced the cross-sectional areas of the speaker's...
