Improving Code-Switching ASR with Code-Mixing Guided Synthetic Speech
A new code-mixing guided preference-learning framework improves code-switching automatic speech recognition (ASR) by steering synthetic speech generation toward better language-boundary consistency. Fine-tuning Whisper Large with this approach reduced Mixed Error Rate (MER) from 12.1% to 8.9% on the DevMAN set and from 17.8% to 14.2% on the DevSGE set of the SEAME Mandarin-English conversational corpus.
