Static and Dynamic Information in Vowels Produced by the Hearing Impaired

By Judith A. Rubin

To understand more about the underlying deviant nature of vowel production by the hearing impaired, hearing and hearing-impaired talkers were compared with respect to (1) intrasubject variability in vowel production and (2) the information used by listeners in decoding their vowels. Results of the acoustic analyses suggest that while intrasubject variability was greater than normal, hearing-impaired talkers were not random in their employment of articulatory gestures for vowel production. Results of the perceptual experiment suggest that listeners use the same acoustic sources of information in decoding vowels by hearing and hearing-impaired talkers.
