摘要:
Previous research has demonstrated that a speaker has a high degree of control over his articulatory behavior when asked to repeat sentences several times in exactly the same way. The present research was designed to investigate the use of auditory cues during phonation. Normal‐hearing speakers were instructed to read each of five sentences 25 times in exactly the same manner. While the speakers were talking, a masking noise was presented binaurally through earphones at several sound‐pressure levels (SPLs) (up to 107 dB SPL), which the speakers were instructed to ignore. Measures of peak and integrated intraoral air pressure, SPL, and total phonation time were made to determine the stability of the utterances. Slight increases in SPL, intraoral air pressure, and phonation time accompanied increases in the masker SPL. However, these increases were minimal in comparison to published data suggesting sensory‐motor information other than auditory was utilized by the speakers to control and maintain constant articulatory behavior.
