Voicebox: Open-Source Speech Recognition Toolkit
An open-source speech recognition toolkit for speech processing research providing algorithms for speech analysis, synthesis, and recognition available for Windows, Mac, and Linux implementation in MATLAB.
What is Voicebox?
Voicebox is an open-source toolkit for speech and audio processing research, implemented in MATLAB. It provides a comprehensive set of over 200 speech analysis, feature extraction, classification, synthesis, and recognition functions.
Some key features of Voicebox include:
- Algorithms for speech analysis like spectrogram, cepstrum, Linear Predictive Coding
- Feature extraction functions like MFCC, PLP, RASTA-PLP
- Speech activity detection, endpoint detection
- Speech synthesis functions using KLSYN88 algorithm
- Isolated word recognition using HMMs
- Speech enhancement algorithms like spectral subtraction, Wiener filtering
Voicebox works on Windows, Mac, and Linux platforms. The toolbox is useful for researchers, academics, and engineers working on speech processing projects to quickly prototype and evaluate different algorithms. It provides modular, well-documented functions that can be easily integrated into larger applications.
Some limitations are that it only focuses on speech processing, lacks support for deep learning models, and has limited visualization capabilities. But overall it is one of the most comprehensive open-source speech toolkits available.
