Voice changer

Learn how to transform audio between voices while preserving emotion and delivery.

Overview

ElevenLabs voice changer API lets you transform any source audio (recorded or uploaded) into a different, fully cloned voice without losing the performance nuances of the original. It’s capable of capturing whispers, laughs, cries, accents, and subtle emotional cues to achieve a highly realistic, human feel and can be used to:

  • Change any voice while preserving emotional delivery and nuance
  • Create consistent character voices across multiple languages and recording sessions
  • Fix or replace specific words and phrases in existing recordings

Best practices

Audio quality

  • Record in a quiet environment to minimize background noise
  • Maintain appropriate microphone levels - avoid too quiet or peaked audio
  • Use remove_background_noise=true if environmental sounds are present

Recording guidelines

  • Keep segments under 5 minutes for optimal processing
  • Feel free to include natural expressions (laughs, sighs, emotions)
  • The source audio’s accent and language will be preserved in the output

Parameters

  • Style: Set to 0% when input audio is already expressive
  • Stability: Use 100% for maximum voice consistency
  • Language: Choose source audio that matches your desired accent and language

FAQ

Yes, but you must split it into smaller chunks (each under 5 minutes). This helps ensure stability and consistent output.

Absolutely. Provide your custom voice’s voice_id and specify the correct model_id.

You’re charged at 1000 characters’ worth of usage per minute of processed audio. There’s no additional fee based on file size.

Possibly. Use remove_background_noise=true or the Voice Isolator tool to minimize environmental sounds in the final output.

Though eleven_english_sts_v2 is available, our eleven_multilingual_sts_v2 model often outperforms it, even for English material.

“Style” adds interpretative flair; “stability” enforces consistency. For high-energy performances in the source audio, turn style down and stability up.
