Long Text Speech Coherence Guarantee Program
For long text synthesis, the following methods are recommended to ensure speech quality:
- Text Preprocessing Strategies::
1. Use the split_pattern parameter to segment semantically (regular expressions are recommended):
"`python
split_pattern=r'n+|[,. ;!?] +'
“`
2. 500ms paragraph interval retained (adjustable via silence parameter) - Phonemic consistency guarantee::
- Capturing and comparing ps (phoneme) output across segments in a Python environment
- Establishment of a phoneme mapping table to harmonize specific pronunciations - aftertreatment technology::
- Audio articulation smoothing with the pydub library
- Add a uniform ambient background sound to mask seams
For very long texts over 10 minutes, it is recommended to generate them in segments before synthesizing them with professional audio tools.
