The Python SDK and docs are currently in beta.
Report issues on [GitHub](https://github.com/OpenRouterTeam/python-sdk/issues).

## Overview

Text-to-speech endpoints

### Available Operations

* [create\_speech](#create_speech) - Create speech

## create\_speech

Synthesizes audio from the input text. Returns a raw audio bytestream in the requested format (e.g. mp3, pcm, wav).

### Example Usage

```python
from openrouter import OpenRouter
import os

with OpenRouter(
    http_referer="<value>",
    x_open_router_title="<value>",
    x_open_router_categories="<value>",
    api_key=os.getenv("OPENROUTER_API_KEY", ""),
) as open_router:

    res = open_router.tts.create_speech(input="Hello world", model="elevenlabs/eleven-turbo-v2", voice="alloy", response_format="pcm", speed=1)

    # Handle response
    print(res)

```
