ElevenLabs Voice Changer: Change a Recording's Voice

Turn one recording into another voice. Paste an HTTPS link to the clip (max 20 MB, up to 5 minutes) and the ElevenLabs voice id; you get the same performance in the new voice, with optional background-noise removal first. Pay only for what you use.

You receive

Returns the run's audio: your clip performed in the selected ElevenLabs voice, after optional background-noise removal. Not text-to-speech, transcription or real-time changing. Billed per use, no subscription; one run is capped at $0.60. The same prepaid wallet funds your next voice conversion.

Start with your task
