Studies show that bilingual speakers can change their voices when they speak an L2 compared to their L1. It remains to be seen whether these differences are perceived by listeners. Thus, the present study addresses the perception of voice quality by Brazilian bilingual listeners in Brazilian Portuguese (PB) and English (IN) speech samples produced by Brazilian bilingual speakers. This objective was reached by means of a discrimination test of the PB and IN voices of the same speaker. The listeners judged whether the voices were the same or different, describing their characteristics if they were different. The results pointed to certain variability in the judgments, but also showed that listeners are able to identify differences in pitch and intensity between languages, as well as attribute personality and emotion characteristics to speech in both languages.
