Audio file URL that takes priority over target_voice in determining the output voice. The fallback when neither target_voice nor target_voice_audio_url is supplied is the default target voice.

Select a voice for speech-to-speech generation, or leave both target_voice and target_voice_audio_url unspecified to have a target voice chosen randomly.

About Chatterboxhd · Speech to Speech

Converts the speech in `source_audio_url` into a different voice. Choose one of nine preset voices with `target_voice`, or supply your own sample through `target_voice_audio_url`, which takes priority. If neither is given, a voice is chosen for you. Setting `high_quality_audio` upscales the output to 48kHz instead of 24kHz.
