audlib 0.0.3.3

A speech signal processing library with emphasis on deep learning.

audlib

A speech signal processing library in Python with emphasis on deep learning.

audlib provides a collection of utilities for developing speech-related applications using both signal processing and deep learning. The package offers the following high-level features:

• Speech signal processing utilities with ready-to-use applications
• Deep learning architectures for speech processing tasks in PyTorch
• PyTorch-compatible interface (similar to torchvision) for batch processing
• A command-line interface with a unix-pipe-like syntax
  • I/O utilities for interfacing with CMUSPHINX

Some use cases of audlib are:

• Extracting common speech features for your backend
• Integrating CMUSPHINX with modern deep learning architectures
• Developing your own deep-learning-based tools for speech tasks
• Quickly try out speech processors and visualize the spectrogram in command line

audlib focuses on correctness, efficiency, and simplicity. Signal processing functionalities are mathematically checked whenever possible (e.g. constant overlap-add, istft(stft(X))==X). Deep neural networks follow the PyTorch's convention.

Breaking Changes
