## Overview

ElevenLabs [voice changer](/guides/changelog-api-reference-text-to-dialogue-convert) 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

Explore our [voice library](https://elevenlabs.io/voice-library) to find the perfect voice for your project.
