[![Streamlit App](https://static.streamlit.io/badges/streamlit_badge_black_white.svg)](https://vocex-demo.streamlit.app)


This model requires the Vocex library, which is available using

```pip install vocex```



Vocex extracts several measures (as well as d-vectors) from audio.

## Usage
```python
from vocex import Vocex
import torchaudio # or any other audio loading library

model = Vocex.from_pretrained('cdminix/vocex') # an fp16 model is loaded by default
model = Vocex.from_pretrained('cdminix/vocex', fp16=False) # to load a fp32 model
model = Vocex.from_pretrained('some/path/model.ckpt') # to load local checkpoint

audio = ... # a numpy or torch array is required with shape [batch_size, length_in_samples] or just [length_in_samples]
sample_rate = ... # we need to specify a sample rate if the audio is not sampled at 22050

outputs = model(audio, sample_rate)
pitch, energy, snr, srmr = (
    outputs["measures"]["pitch"], 
    outputs["measures"]["energy"],
    outputs["measures"]["snr"],
    outputs["measures"]["srmr"],
)
d_vector = outputs["d_vector"] # a torch tensor with shape [batch_size, 256]

# you can also get activations and attention weights at all layers of the model
outputs = model(audio, sample_rate, return_activations=True, return_attention=True)
activations = outputs["activations"] # a list of torch tensors with shape [batch_size, layers, ...]
attention = outputs["attention"] # a list of torch tensors with shape [batch_size, layers, ...]

# there are also speaker avatars, which are a 2D representation of the speaker's voice
outputs = model(audio, sample_rate, return_avatar=True)
avatar = outputs["avatars"] # a torch tensor with shape [batch_size, 256, 256]
