The Difference ◽  
Intraoral Pressure

Peak intraoral air pressure and flow were measured simultaneously for the syllables /pa/and/ba/in two speaking conditions (syllable repetitions, and in carrier phrases) and in two phonation modes (normal phonation and whisper). Results indicated that 1) the difference between the intraoral air pressure for/p/and/b/was statistically significant in normal phonation, but not in whisper, 2) the difference in peak flow for/p/and /b/was statistically significant in both normal phonation and whisper, and 3) the pressure and flow data were unaffected by speaking conditions. These data, plus a subsequent analysis of intraoral pressure slopes, are taken to indicate that the voiceless and voiced members of a stop-cognate pair are produced in whisper with unique laryngeal gestures.

Parameters Of Interest

Intraoral air pressure, volume rate of airflow, and sound pressure level were measured during /∫/ and /s/ productions of two speakers. In addition numerical estimates of the loudness of the productions were made by each speaker and by a group of judges. The power laws governing the relations among the parameters of interest are discussed and the results are compared with available data on voice production.

A comparison of the ranges of levator veli palatini EMG activity for speech versus a nonspeech task for subjects with cleft palate was the focus of this study. EMG values are also compared with subjects without cleft palate obtained in a previous study. Hooked-wire electrodes were inserted into the levator muscle of five adult subjects with cleft palate exhibiting mild hypernasality. Intraoral air pressure was measured concurrently. A blowing task was used to determine the subject's operating range for the levator muscle. Both the nonspeech and speech tasks were designed to sample the widest possible ranges of levator EMG activity. It was found that the subjects with cleft palate used a relatively high activation level for the levator muscle during speech, in relation to their total activation range, compared with the subjects without cleft palate. Implications are discussed In relation to possible anatomic and physiologic differences for cleft palate subjects compared to normal.
