The Relationship Between Intensity and Subglottal Pressure with Controlled Pitch

This paper present a study of the relationship between subglottal pressure (SGP) and intensity of the speech signal in the case of sustained French oral vowels with controlled pitch. The corpus is based on a male and a female subjects, the SGP is measured directly by tracheal puncture. The results show that the relationship between intensity and subglottal pressure varies when one considers the vowel or the pitch parameter. This experiment is useful in the framework of speech production model design. These preliminary results emphasize the need to investigate thoroughly the relationship between all the parameters involved and to do s o on abundant and accurate experimental data.
