Speech Naturalness Optimization Solution
To improve the quality of speech output, the following dimensions can be optimized:
- Character SelectionEnglish recommends the use of the tara character, whose speech is the most natural; Chinese needs to test the performance of different characters.
- Labeling: Expression is enhanced by emotion tags such as , , etc. It is recommended to insert 1 tag every 20-30 characters.
- fine-tuned model: Prepare 300 high-quality samples for fine-tuning, focusing on rhythmic features of the target language.
- post-processing: Use audio editing software to adjust parameters such as speech rate (±15%) and pitch (±3 semitones) of the generated audio.
Suggestions: 1) Test with the basic model first 2) Add emotion labels step by step 3) Consider model fine-tuning in the end. Note that multi-language models need to refer to the official document to adjust the parameters.
