The aim of this study was to investigate the pitch and formant characteristics of vowels produced by monolingual and bilingual children. We collected sustained phonation of single vowels, /a/, /i/, /u/, from children aged 6 through 10 and compared their acoustic characteristics, fo, F1, F2. Results showed a significant difference between the groups in fo and F1 in the sustained phonation /a/, but not in F2. In the sustained phonation /i/, F2 revealed a significant difference but fo and F1 showed no significant difference. The F2 showed a significant difference in the sustained phonation /u/, but fo and F1 revealed no significant difference between the groups. It is needed to study further on the acoustic characteristics of bilingual children so that we can make a proper language intervention strategy for them.
