Chinese Tone Optimization Program
The following solutions can be used to address the Chinese-specific four-tone problem:
- data enhancement: Training data labeled with pinyin is added for fine-tuning, and at least 500 samples labeled with tones are recommended.
- Post-processing correction: Rhyme correction of the generated audio using tools such as PaddleSpeech.
- Cue word optimization: Add pinyin comments to the text, such as "ni3 hao3″ instead of "hello".
- Model Selection: Priority is given to the zh-cn-specific version of the multilingual model.
Operation Procedure: 1) Test the basic model performance 2) Collect problematic audio samples 3) Targeted fine-tuning 4) Combine with post-processing if necessary. Note that Chinese requires 20% more training data than English to achieve the same effect.
