Is there adaptation of speech production after speech perception in bilingual interaction?

In dialogue, speakers tend to adapt their speech to the speech of their interlocutor. Adapting speech production to preceding speech input may be particularly relevant for second language (L2) speakers interacting with native (L1) speakers, as adaptation may facilitate L2 learning. Here we asked whether Dutch-English bilinguals adapt pronunciation of the English phonemes /æ/ and coda /b/ when reading aloud sentences after exposure to native English speech.

Anatomical and functional changes in the brain after simultaneous interpreting training: A longitudinal study.

In the recent literature on bilingualism, a lively debate has arisen about the long-term effects of bilingualism on cognition and the brain. These studies yield inconsistent results, in part because they rely on comparisons between bilingual and monolingual control groups that may also differ on other variables. In the present neuroimaging study, we adopted a longitudinal design, assessing the long-term anatomical and cognitive effects of an extreme form of bilingualism, namely simultaneous interpreting.
