pytorch-speech-features 0.0.3

PyTorch Speech Feature extraction

pytorch_speech_features

A simple PyTorch reimplementation of library python_speech_features.

Uses

• Great for Intepretability experiments - All audio processing operations can be performed and the results can be backpropagated to the original signal tensor.
• Supports Hybrid Model Design - Parametric operations at different stages of audio processing.

Example use

Installation

Install from PyPI

pip install pytorch-speech-features

Install from GitHub

git clone https://github.com/Debjoy10/pytorch_speech_features
python setup.py develop

Usage

Functions same as python_speech_features (Refer to its documentation here).

Instead of input signal as list / numpy array, pass tensor (both 'cpu' and 'cuda' supported!!).

See example use given above.

Supported features:

• Mel Frequency Cepstral Coefficients
• Filterbank Energies
• Log Filterbank Energies
• Spectral Subband Centroids

Testing

Two things to test for pytorch_speech_features operations -

1. Similarity to python_speech_features outputs.
2. Gradient correctness via Autograd Gradcheck.
