# Whisper Speech Recognition

> Transcribe audio to text with OpenAI Whisper on DeepInfra.

[Whisper](https://github.com/openai/whisper) is OpenAI's speech recognition model. Given an audio file, it produces transcribed text with per-sentence timestamps. DeepInfra hosts multiple Whisper variants.

## Models

| Model                               | Notes               |
| ----------------------------------- | ------------------- |
| `openai/whisper-large`              | Best accuracy       |
| `openai/whisper-medium`             | Balanced            |
| `openai/whisper-small`              | Fast                |
| `openai/whisper-base`               | Smallest            |
| `openai/whisper-timestamped-medium` | Per-word timestamps |

By default, Whisper produces per-sentence timestamp segmentation. `whisper-timestamped` gives per-word timestamps.

## Example

<CodeGroup>
  ```javascript JavaScript theme={null}
  import { AutomaticSpeechRecognition } from "deepinfra";
  import path from "path";
  import { fileURLToPath } from "url";

  const __filename = fileURLToPath(import.meta.url);
  const __dirname = path.dirname(__filename);

  const client = new AutomaticSpeechRecognition(
    "openai/whisper-large",
    "$DEEPINFRA_TOKEN"
  );

  const response = await client.generate({
    audio: path.join(__dirname, "audio.mp3"),
  });

  console.log(response.text);
  ```

  ```bash cURL theme={null}
  curl -X POST \
      -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
      -F audio=@audio.mp3 \
      'https://api.deepinfra.com/v1/inference/openai/whisper-large'
  ```
</CodeGroup>

## Supported formats

* `mp3`
* `wav`

## Additional parameters

Each Whisper variant supports parameters like `language`, `task` (transcribe vs. translate), and more. Check the model's documentation page for the full list:
