SHORT-TERM VARIATION OF SUBGLOTTAL PRESSURE FOR EXPRESSIVE PURPOSES IN SINGING AND STAGE SPEECH - A PRELIMINARY INVESTIGATION

According to previous investigations, subglottal pressure in singing i s adapted not only to loudness but also to fundamental frequency. Here the significance of musical expression to subglottal pressure is anal yzed in terms of alternations between stressed and unstressed bar posi tions. Esophageal pressure was recorded together with the audio signal in a male and a female professional singer using a paranasally introd uced pressure transducer while the subjects performed vocal exercises. Also, the subjects gave examples of actors' speech by reading poetry aloud. The results show that subglottal pressure can be used for stres sing the first beat in bars and also for increasing the sound level in voiced consonants in actor's speech.
