New T-SANDHI model improves Taiwanese Hokkien speech recognition

By PulseAugur Editorial · [1 sources] ·

Researchers have developed T-SANDHI, a novel approach to improve automatic speech recognition for low-resource Taiwanese Hokkien. Unlike previous assumptions that tone sandhi is the primary challenge, this new method identifies localized confusion between tone variations and citation tones as the main performance bottleneck. T-SANDHI works by decoupling surface acoustics from underlying lexical intent on a frozen Whisper model, using a hybrid injection module with dynamic gating to integrate phonetic streams. Evaluations on the TAT-MOE corpus show that this method significantly enhances accuracy and parameter efficiency. AI

IMPACT This research offers a new method for improving speech recognition in low-resource languages by addressing specific phonetic challenges.

    T-SANDHI: Tone Sandhi-aware Adaptive Network with Decoupled Hybrid Injection for Low-resource Taiwanese Hokkien Speech Recognition

    arXiv:2609.18194v1 Announce Type: new Abstract: In Taiwanese Hokkien automatic speech recognition (ASR), prior studies often treat tone sandhi as a major challenge under the assumption that models fail to process implicit phonological variations. However, our experiments on Taiwa…
