This investigation explored respiratory differences between a speaker’s first language (L1) and second language (L2) during spontaneous and scripted speech in six adult bilingual speakers (two native bilingual speakers and four non-native bilingual speakers). Respiratory kinematic data using Respitrace respiratory inductance plethysmography and acoustic recordings were collected during five tasks: tidal breathing at rest, scripted speech in L1, spontaneous speech in L1, scripted speech in L2, and spontaneous speech in L2. Results indicated a significant interaction effect between proficiency and syllables produced during spontaneous speech, but no other significant differences were found among inspiratory/expiratory duration, task, proficiency or language. The data provides insight into how a higher cognitive-linguistic load of speaking in a second language may affect speech breathing and contributes to the existing pool of knowledge on monolingual cognitive-linguistic demands and speech breathing.
