# Edit voice settings

POST https://api.elevenlabs.io/v1/voices/{voice_id}/settings/edit
Content-Type: application/json

Edit your settings for a specific voice. "similarity_boost" corresponds to "Clarity + Similarity Enhancement" in the web app and "stability" corresponds to "Stability" slider in the web app.

Reference: https://elevenlabs.io/docs/api-reference/voices/settings/update

## Servers

- `https://api.elevenlabs.io` (Production, default)
- `https://api.us.elevenlabs.io` (Production US)
- `https://api.eu.residency.elevenlabs.io` (Production EU)
- `https://api.in.residency.elevenlabs.io` (Production India)
- `https://api.sg.residency.elevenlabs.io` (Production Singapore)

## Request

### Path parameters

- `voice_id` (string, required) — ID of the voice to be used. You can use the [Get voices](/docs/api-reference/voices/search) endpoint list all the available voices.

### Body (application/json)

This endpoint expects a VoiceSettingsResponseModel.

- `stability` (double, optional, nullable, default: 0.5) — Determines how stable the voice is and the randomness between each generation. Lower values introduce broader emotional range for the voice. Higher values can result in a monotonous voice with limited emotion.
- `use_speaker_boost` (boolean, optional, nullable, default: true) — This setting boosts the similarity to the original speaker. Using this setting requires a slightly higher computational load, which in turn increases latency.
- `similarity_boost` (double, optional, nullable, default: 0.75) — Determines how closely the AI should adhere to the original voice when attempting to replicate it.
- `style` (double, optional, nullable, default: 0) — Determines the style exaggeration of the voice. This setting attempts to amplify the style of the original speaker. It does consume additional computational resources and might increase latency if set to anything other than 0.
- `speed` (double, optional, nullable, default: 1) — Adjusts the speed of the voice. A value of 1.0 is the default speed, while values less than 1.0 slow down the speech, and values greater than 1.0 speed it up.

## Response

### 200

Successful Response

- `status` (string, required) — The status of the voice settings edit request. If the request was successful, the status will be 'ok'. Otherwise an error message with status 500 will be returned.

## Errors

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
- `type` (string, required)

### ValidationErrorLocItems
