A complete solution for optimizing sound similarity
Although the CSM-1B model is not able to achieve full fidelity, the similarity can be significantly improved by the following methods:
- Audio Sample Preparation
Recording 3 minutes of pure vocals is recommended:- Using professional microphones in quiet environments
- Includes the ebb and flow and pauses of natural speech
- Avoid background music and clutter
- Parameter tuning strategy
Modify voice_clone.py:- Increase the number of num_repetitions (default 3 can be changed to 5)
- Debugging the temperature parameter (try between 0.7 and 1.2)
- Post-processing techniques
Use Audacity on the output audio:- Adjust EQ to match acoustic frequency
- Add a slight reverb to enhance realism
- Eliminate Model Generation Noise with Noise Reduction
