Change Voice
change_voiceTake a recording of someone speaking and have it said again in a different voice, keeping the original performance exactly: the pauses, the timing, the emphasis and the feeling all stay, only who is speaking changes. Give it source (a recording in your library by id, or an https link to one) and voice (a voice name or a voice id from list_voices). Use "multilingual" (the default) for any language, "english" for an English-only take. Turn remove_background_noise on when the recording has room noise, traffic or hiss behind the speaker. Billed per 10 seconds of audio. This is for re-voicing a real performance; to speak written words from scratch use generate_speech.
