Guide title

Check a WAV voice reference clip with Python alone before you clone a voice with Chatterbox: format, length against the 5 s, 10 s and 6 s windows its code uses, level, clipping and silence, without running the model

Coverage

Made for anyone about to give a WAV voice sample to a voice-cloning text-to-speech program. A short script reads the file without any model and reports the format, the length, the peak and average level, clipped samples and silence, and how many seconds of the clip each Chatterbox code path takes, as read from its source code, with an exit code. Honest limits: it was tried only on made-up tones, never on speech, the Chatterbox model was never run, and it cannot tell whether the clip is a good voice sample or whether the speaker agreed.

Example

On built files it told a clip of exactly 5.0 seconds from one of 5.01 seconds for the Turbo code, caught a data size field that runs past the end of the file, 0.1% clipped samples and a clip whose first 10 seconds are 31% silent, and in every one of 35,356 cuts of three small files it reported a problem or a notice.

Useful starting points

• Say where the clip came from and who agreed to its use.
• Keep the clip longer than 5 seconds and the first 10 seconds clear.
• Treat a clean report as a first look only.
