Late bilinguals show more native language (L1) influence on English sound production and perception than early bilinguals. This L1 transfer impacts their English /b/, /d/, and /g/ sounds, likely due to less English phonetic input.

Area of Science:

  • Phonetics and Second Language Acquisition
  • Bilingualism Research
  • Speech Perception and Production

Background:

  • Bilinguals often exhibit native language (L1) influence on their second language (L2) phonology.
  • Age of arrival (AOA) is a critical factor in L2 sound system development.
  • Understanding L1 transfer in bilingual speech production and perception is crucial for L2 pedagogy.

Purpose of the Study:

  • To investigate the impact of AOA and L1 use on English stop consonant (/b/, /d/, /g/) production and perception in bilinguals.
  • To compare early and late bilinguals' phonetic behavior with native English (NE) speakers.
  • To determine if L1 phonetic patterns influence L2 sound realization and identification.

Main Methods:

  • Examined English /b/ production and perception of short-lag English /b d g/ tokens in four bilingual groups.

Related Experiment Videos

  • Categorized participants by AOA in Canada from Italy and self-reported L1 use.
  • Utilized phonetic analysis of prevoicing frequencies and perceptual identification tasks.

    • Main Results:

    • Late bilinguals (AOA=20 years) exhibited greater L1 influence than early bilinguals (AOA=8 years) in both production and perception.
    • Late bilinguals produced more prevoiced /b/ tokens and misidentified short-lag /b d g/ tokens more frequently than early bilinguals and NE speakers.
    • Prevoicing frequencies in L1 Italian and L2 English were correlated across bilingual groups.

    Conclusions:

    • Differences between early and late bilinguals are attributed to the quantity and quality of English phonetic input received.
    • Early L2 phonetic learning does not necessarily involve establishing entirely new phonetic categories.
    • L1 phonetic habits persist and influence L2 sound system development, particularly in late bilinguals.
