# ElevenLabs Speech to Speech

> Transform an existing audio recording into a different voice or style while preserving content and delivery using ElevenLabs in ComfyUI.

Take an existing audio recording and transform it into a different voice or style while preserving the spoken content and delivery. Speech to Speech retains the original intonation, pacing, and emotional delivery while applying a new voice identity.

## Key capabilities

* **Preserve delivery** — Retain original intonation, pacing, and emotional expression
* **Voice transformation** — Apply a different voice identity to existing audio
* **Style transfer** — Change the vocal style or character without re-recording
