Acquiring French Intonation against the Backdrop of Heritage Bilingualism: The Case of German–Turkish Learners

Abstract

This paper investigates the intonation of L3 French, produced by six bilingual learners (ages: 15–17) who speak Turkish as a heritage language (HL) along with German and six same-aged monolingual German learners. We examined of a corpus of read speech in two respects: first, we determined the number of accentual phrases (APs) and, second, we extracted F0 values for each segment, normalized them, and calculated the deviations from the average values produced by three native controls (age: 21–23). Although the bilinguals were expected to outperform the monolinguals due to certain similarities between the intonational systems of French and Turkish, their mean deviation from the native contours was only slightly smaller than that of the monolinguals (difference not significant). To determine how strongly the bilinguals’ Turkish intonation was influenced by German and whether it could serve as a basis for positive transfer whatsoever, we compared their production in Turkish with data recorded from three monolingual Turkish L1 speakers (ages: 21–32) and five German learners of L2 Turkish (ages: 22–43). Results show that the bilinguals’ Turkish intonation does not deviate substantially from the monolinguals’ one, in contrast to the contours produced by the L2 learners. This suggests that metalinguistic and prosodic awareness should be fostered in heritage bilinguals to make them benefit from their full linguistic repertoire.
