To understand whether these differences extend to prosody we study F0 variation in a corpus of interviews with German-Italian and German-French bilingual speakers. We find two primary effects. First, a betweenspeaker effect: these two groups of bilinguals make different use

Second, a within-speaker effect: bilinguals use F0 differently depending on which language they are speaking, differences that are consistent across speakers. These effects are modulated strongly by gender, suggesting that language-specific social positioning may play a central role. These results have important implications for our understanding of bilingualism and cross-cultural linguistic difference in general. Prosody appears to be a moving target rather than a stable feature, as speakers use prosodic variation to position themselves on cultural and social axes like linguistic context and gender.
