The majority of Indonesians are bilingual, speaking a regional language and the national language, Indonesian. It is often assumed that in the use of either language, the influence of the other manifests itself; yet systematic documentation of such influence is lacking. In this study, the Indonesian of Javanese/Indonesian bilinguals is compared with that of monolingual Indonesian speakers, using vowel height as a case study to assess the phonetic effects of this influence. The results show that high vowels in CVCs are lower and more centralized than in CVs. For the bilinguals, /i/'s in CVCs overlap with /e/'s in the acoustic space, while /u/'s in CVCs are as low as but more centralized than /o/'s. I argue that this is the realization of Javanese vowel centralization on the Indonesian of the bilinguals. Vowel duration is shorter in CVCs than in CVs, which may enhance the perceived vowel centralization of the bilinguals.
