Streaming transcriber with [whisper](https://github.com/openai/whisper).
Enough machine power is needed to transcribe in real time.

## Setup

```bash
pip install -U git+https://github.com/shirayu/whisper_streaming.git

# If you use GPU, install proper torch and torchaudio with "poetry run pip install -U"
# Example : torch for CUDA 11.6
pip install -U torch torchaudio --extra-index-url https://download.pytorch.org/whl/cu116
```

## Example of microphone

```bash
# Run in English
poetry run whisper_streaming --language en --model tiny
```

- ``--help`` shows full options
- ``--language`` sets the language to transcribe. The list of languages are shown with ``poetry run whisper_streaming -h``
- ``-t`` sets temperatures to decode. You can set several like (``-t 0.0 -t 0.1 -t 0.5``), but too many temperatures exhaust decoding time
- ``--debug`` outputs logs for debug

### Parse interval

If you want quick response, set small ``-n`` and add ``--allow-padding``.
However, this may sacrifice the accuracy.

```bash
poetry run whisper_streaming --language en --model tiny -n 20 --allow-padding
```

## Example of web socket

⚠  **No security mechanism. Please make secure with your responsibility.**

Run with ``--host`` and ``--port``.

### Host

```bash
poetry run whisper_streaming --language en --model tiny --host 0.0.0.0 --port 8000
```

You can set ``--allow-padding`` and other options.

### Client

```bash
poetry run whisper_streaming --model tiny --host ADDRESS_OF_HOST --port 8000 --mode client
```

You can set ``-n`` and other options.

## Tips

## PortAudio Error

If you get ``OSError: PortAudio library not found``: Install ``portaudio``

```bash
# Ubuntu
sudo apt-get install portaudio19-dev
```
