## Overview

Speech-to-text endpoints

### Available Operations

* [create_transcription](#create_transcription) - Create transcription
* [create_transcription_multipart](#create_transcription_multipart) - Create transcription

## create_transcription

Transcribes audio into text. Accepts base64-encoded audio input as JSON or an OpenAI-style multipart/form-data file upload, and returns the transcribed text.

### 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.stt.create_transcription(input_audio={
        "data": "UklGRiQA...",
        "format_": "wav",
    }, model="openai/whisper-large-v3", language="en")

    # Handle response
    print(res)

```

### Parameters
