Syllabic rhythm is key for distinguishing languages like English and Japanese, even for adults. This study introduces a new method to test how acoustic cues affect language discrimination in bilingual environments.

Area of Science:

  • Psycholinguistics
  • Speech Perception
  • Acoustic Phonetics

Background:

  • Understanding language discriminability is crucial for children in bilingual environments.
  • Previous research explored language discrimination using methods like low-pass filtered speech.
  • Phonological theories suggest rhythmic differences between languages play a significant role.

Purpose of the Study:

  • To introduce and validate a novel experimental paradigm for studying language discriminability.
  • To investigate the role of specific acoustic cues (phonotactics, syllabic rhythm, intonation) in differentiating languages.
  • To assess the effectiveness of speech resynthesis in manipulating these acoustic cues.

Main Methods:

  • Developed a speech resynthesis technique to preserve or degrade acoustic cues from natural utterances.

  • Resynthesized English and Japanese sentences under four conditions: full cues, rhythm & intonation, intonation only, rhythm only.
  • Tested French adult subjects on their ability to discriminate between the resynthesized languages.

    • Main Results:

    • Syllabic rhythm was identified as a necessary and sufficient cue for French adults to discriminate between English and Japanese sentences.
    • Results align with prior studies using filtered speech and phonological theories on rhythmic language differences.
    • The proposed speech resynthesis paradigm proved effective for language discrimination research.

    Conclusions:

    • Syllabic rhythm is a primary acoustic cue for distinguishing between languages like English and Japanese.
    • The novel experimental paradigm using speech resynthesis is a valuable tool for psycholinguistic research on language perception.
    • This methodology has potential applications in automatic language identification and understanding early bilingual language acquisition.
