# 🎙️🥁🚨🔊 Brouhaha

![Sample Brouhaha predictions](brouhaha.gif)

**Joint voice activity detection, speech-to-noise ratio, and C50 room acoustics estimation**

[TL;DR](https://twitter.com/LavechinMarvin/status/1585645131251605504) | [Paper](https://arxiv.org/abs/2210.13248) | [Code](https://github.com/marianne-m/brouhaha-vad) | [And Now for Something Completely Different](https://www.youtube.com/watch?v=8ZyOAS22Moo)



## Installation

This model relies on [pyannote.audio](https://github.com/pyannote/pyannote-audio) and [brouhaha-vad](https://github.com/marianne-m/brouhaha-vad).

```bash
pip install pyannote-audio
pip install https://github.com/marianne-m/brouhaha-vad/archive/main.zip
```

## Usage

```python
# 1. visit hf.co/pyannote/brouhaha and accept user conditions
# 2. visit hf.co/settings/tokens to create an access token
# 3. instantiate pretrained model
from pyannote.audio import Model
model = Model.from_pretrained("pyannote/brouhaha", 
                              use_auth_token="ACCESS_TOKEN_GOES_HERE")

# apply model 
from pyannote.audio import Inference
inference = Inference(model)
output = inference("audio.wav")

# iterate over each frame
for frame, (vad, snr, c50) in output:
    t = frame.middle
    print(f"{t:8.3f} vad={100*vad:.0f}% snr={snr:.0f} c50={c50:.0f}")

#  ...
# 12.952 vad=100% snr=51 c50=17
# 12.968 vad=100% snr=52 c50=17
# 12.985 vad=100% snr=53 c50=17
# ...
```
