The Interplay between Speech and Breathing across three Brazilian Portuguese Speaking Styles

Plinio Barbosa, Sandra Madureira


This paper introduces the first study on the coordination between breathing and speech in Brazilian Portuguese. Four subjects (two males and two females) were recorded by using the RespTrack device, which allows the measure of the breathing cycle and the simultaneous recording of speech. In order to shed light on the interplay between the two activities, three speaking styles were investigated: reading, narration of story and commentary of story characters. Five parameters were measured: breath cycle duration, duration and amplitude of Inhalation, duration to speech onset from onset of breath cycle or from peak of inhalation. Results showed stylistic and gender differences: coordination differs between reading and the other two styles; breath cycles are shorter by 1 to 1.5 second in reading; commentary does not differ between the two genders for four out of five parameters; differences between males and females are found in four out of five parameters measured, excepted breath cycle duration, and are interpreted as related to differences in thoracic volume.
