# Configuring Voice Settings

> Fine-tune text-to-speech settings for ElevenLabs and Fish Audio

Voice settings are configured under `avatar_persona.voice_settings` when creating a session token. LiveAvatar supports two TTS providers.

## Shared Settings

These apply to all providers:

| Parameter | Type   | Range   | Default | Description                                            |
| --------- | ------ | ------- | ------- | ------------------------------------------------------ |
| `speed`   | number | 0.8–1.2 | 1       | Speaking speed. Below 1 slows down, above 1 speeds up. |

## ElevenLabs

| ------------------- | ------- | ----- | ------- | -------------------------------------------------------------- |
| `stability`         | number  | 0–1   | 0.75    | Voice consistency. Higher = more predictable.                  |

| `style`             | number  | 0–1   | 0       | Style intensity exaggeration.                                  |
| `use_speaker_boost` | boolean | —     | true    | Voice clarity enhancement.                                     |
| `model`             | string  | —     | —       | `eleven_flash_v2_5` (low latency) or `eleven_multilingual_v2`. |

## Fish Audio
