  title: ElevenLabs Voice Cloning Professional Voice Cloning API
  description: The ElevenLabs Voice Cloning API allows developers to create custom AI voices from audio recordings. Instant Voice Cloning requires as little as 60 seconds of clean audio to generate a usable voice clone, while Professional Voice Cloning produces higher fidelity results from a minimum of 30 minutes of recordings. Cloned voices can then be used with the Text to Speech API for generating speech that closely matches the original speaker.
