This study introduces novel methods for Chinese dialect identification using speech features. Combining phonetic and prosodic analysis achieved 93.0% accuracy in distinguishing Taiwanese dialects.

Area of Science:

  • Computational Linguistics
  • Speech Processing
  • Phonetics

Background:

  • Accurate Chinese dialect identification is crucial for various applications.
  • Existing methods often focus on either segmental or prosodic features independently.

Purpose of the Study:

  • To develop and evaluate novel approaches for Chinese dialect identification.
  • To investigate the effectiveness of combining segmental and prosodic speech features.
  • To improve the accuracy of discriminating between major Chinese dialects in Taiwan.

Main Methods:

  • Phonotactic analysis of tokenized broad phonetic sequences for segmental information.
  • Development of prosodic models to capture dialect-specific tone sequences.
  • A novel approach integrating both broad phonetic and prosodic feature analysis.

  • Evaluation using a multispeaker read-speech dataset.

    • Main Results:

    • Segmental analysis alone achieved a certain level of dialect discrimination.
    • Prosodic models captured distinctive tone sequence information for dialects.
    • The integrated approach combining segmental and prosodic features yielded the highest accuracy.
    • The system successfully discriminated among three major Chinese dialects in Taiwan with 93.0% accuracy.

    Conclusions:

    • The combination of segmental and prosodic features significantly enhances Chinese dialect identification accuracy.
    • The proposed integrated approach offers a robust solution for distinguishing between closely related Chinese dialects.
    • This research contributes to advancements in automatic speech recognition and language processing for diverse Chinese dialects.
