Overview

Randomized trial investigates fricative production in heritage and second language speakers, showing varied outcomes.

Key Points

  • The study aims to investigate the production of voiceless fricatives by heritage speakers in comparison to native and L2 speakers of Japanese.
  • Examined two voiceless fricatives—bilabial and palatal—in Japanese.
  • Measured acoustic correlates of fricatives from loan and non-loan Japanese words.
  • Compared productions of heritage speakers with native and second language speakers.
  • Heritage speakers produced fricatives that were more native-like than those produced by L2 speakers.
  • Variability in fricative production was noted among heritage speakers based on their language exposure.
  • The findings indicate that early language environment significantly impacts phonetic production.
