This error means the TTS preview engine did not create the expected .wav file. The cause is not visible in this trace, so we need the actual TTS engine log to confirm.

Likely possibilities for your setup (tts_type=3, role=zh_female_tw.wav, language=vi):

1. The selected TTS channel does not support Vietnamese with the current model.

   • If this is F5-TTS, the base Chinese/English model cannot output Vietnamese. A dedicated Vietnamese model must be downloaded.

2. The reference audio file zh_female_tw.wav is missing, is not a valid WAV, or is not in the required location.

   • Check that the file exists in the f5-tts folder and is a 3–10 second, clear single-speaker WAV.
3. The required TTS model files are incomplete or not downloaded.

Please try:

1. Switch to a standard Edge-TTS Vietnamese voice (e.g. vi-VN-HoaiMyNeural) and test again. If that works, the problem is model/reference-audio related.
2. Verify the zh_female_tw.wav file is present and playable.
3. Re-test with a short Chinese text and the same role; if that also fails, the issue is with the reference audio or model, not Vietnamese.

If it still fails, provide the last ~30 lines of the newest log file in C:/Users/pv/Desktop/win-pyvideotrans-v4.10/logs/ so we can identify the underlying TTS error.

Please consult the relevant documentation:

• F5-TTS
• Manual model downloads
