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

Explore our voice library to find the perfect voice for your project.
