# normalize_text

> Preview how Rime normalizes text before synthesis via the MCP server.

Preview how Rime normalizes text before synthesis — exactly what the TTS model will speak. Useful for debugging numbers, dates, phone numbers, currency, and abbreviations. Returns the normalized string.

**API key:** Required — see [Authentication](/mcp-reference/authentication).

## Parameters

| Parameter | Type   | Required | Description           |
| --------- | ------ | -------- | --------------------- |
| `text`    | string | Yes      | The text to normalize |

## Example

Ask your assistant:

```
How will Rime read "Your appointment is on 3/4 at 2:30pm, call 555-0123 to reschedule"?
```

The assistant calls `normalize_text` and shows the spoken form, so you can catch surprises (like `3/4` reading as a date versus a fraction) before synthesis.
