# list_voices

> List Rime's voice catalog by model and language via the MCP server.

List Rime's voice catalog as JSON keyed by model and language: `{ modelId: { langCode: [speaker, ...] } }`. Optionally filter by model and/or language, and cap the output size with `limit`. Use [`get_voice_details`](/mcp-reference/get-voice-details) for demographics and the exact `lang` value to pass to [`synthesize_speech`](/mcp-reference/synthesize-speech).

**API key:** Not required.

## Parameters

| Parameter  | Type    | Required | Description                                                                                                                                           |
| ---------- | ------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model`    | string  | No       | Filter to a single model ID, e.g. `coda`                                                                                                              |
| `language` | string  | No       | Filter to an ISO 639-2 language key, e.g. `eng`                                                                                                       |
| `limit`    | integer | No       | Maximum speakers returned per model+language list. When a list is truncated, the result notes how many speakers were omitted and how to see the rest. |

## Example

Ask your assistant:

```
What Spanish-speaking Coda voices does Rime have?
```

The assistant calls `list_voices` with `model: "coda"` and `language: "spa"` and reads the speaker names from the result.
