Introduction

Learn how to transform audio from one voice into another. The Voice Conversion integration allows your app to convert spoken audio into a different voice using ElevenLabs Speech-to-Speech technology. This enables powerful features such as voice transformation, dubbing, and accent modification while preserving the original speech timing and intent. This integration is ideal for apps that work with audio content, storytelling, media editing, or creative voice experiences.

​
What You Can Build

With Voice Conversion enabled, your app can support features such as:
  • Voice Transformation – Convert a user’s voice into a different voice style or identity.
  • Dubbing Tools – Replace original voice audio in videos or recordings while maintaining timing.
  • Accent Modification – Adjust how speech sounds by changing accents or tone.
  • Character Voices – Create unique voices for storytelling, games, or creative applications.
  • Audio Personalization – Allow users to customize how their voice sounds across the app.

​
How It Works

When the Voice Conversion integration is enabled, your app sends audio input to ElevenLabs Speech-to-Speech, which transforms the original voice into a new one. Your app can:
  • Capture or upload voice recordings
  • Convert speech into a different voice
  • Preserve timing, pacing, and emotion
  • Generate high-quality transformed audio
This allows you to build advanced voice experiences without needing to train or manage voice models. Because voice transformation is handled by ElevenLabs, you can focus on how users interact with and apply voice changes in your app.

Example Prompts

You can use prompts like these when building your app: Add a voice transformer Add a voice transformer to my app that converts a user’s recording into a different voice using ElevenLabs.
