Laryngealization, Gender and Speakers' Distinctiveness in Brazilian Portuguese

Julio Cesar Cavalcanti de Oliveira, Luciana Lucente, Plinio Barbosa


"This work aims to analyze how the occurrence of laryngealization in Brazilian Portuguese can contribute to a speaker characterization, through the analysis of laryngealization rates and its occurrence in vowel and consonantal segments, in order to verify which measures would be more representative of a personal speech style. This work also aims at analyzing the influence of gender on the laryngealization rates. The corpus consists of semi-spontaneous speech records of 10 speakers, five men and five women, who speak the same dialect, ages ranging from 20 to 26 years old, all of them with a high school degree. These recordings are composed by the retelling of a story titled ""Pear Film"", a 6-minutes short film. Speech data were segmented and analyzed using the software Praat. Laryngealization was identified by hearing in vocalic and consonantal segments by the first author, a speech therapist, and confirmed by waveform and spectrogram inspection. Results show a significant distinction in the occurrence of laryngealization between speakers, which may suggest that laryngealization rates could be relevant for speaker comparison. The results related to gender have revealed higher laryngealization rates for females."
