Abstract:
Control of acoustic intensity is required for both linguistic and paralinguistic aspects of speech communication. While generally recognized that deaf speakers experience difficulty learning to control acoustic intensity, the characteristics and mechanisms of intensity control among deaf speakers are not well understood. The objectives of the present research were to: (1) study and describe characteristics of intensity control by deaf individuals during speech production; (2) compare deaf and normal-hearing speaker's control of acoustic intensity; and (3) suggest possible mechanisms used by deaf speakers to control acoustic intensity. Deaf and normal-hearing speakers produced sustained vowels at different acoustic intensity and fundamental frequency levels. The average airflow, acoustic intensity, spectral characteristics, fundamental frequency, and characteristics of vocal fold oscillation were measured. Results showed that deaf speakers tended to use greater than normal air flow for all speaking tasks. While normal-hearing speakers tended to increase airflow with increased intensity, the deaf speakers often failed to produce such a distinction. However, certain systematic changes in laryngeal adjustments associated with increased acoustic intensity were observed in both groups of speakers. Possible mechanisms for intensity control will be discussed, along with clinical implications.
