Speech Coding MATLAB Toolbox

This article introduces a highly practical Speech Coding MATLAB Toolbox designed for various applications including speech coding, speech compression, and speech recognition. Compared to other speech coding tools, this MATLAB toolbox offers superior accuracy and efficiency in speech processing operations. The toolbox incorporates multiple algorithms such as Linear Predictive Coding (LPC), Code-Excited Linear Prediction (CELP), and Adaptive Differential Pulse Code Modulation (ADPCM), providing users with flexible implementation options through configurable function parameters. Key functions include frame-based speech analysis, feature extraction using MFCC (Mel-Frequency Cepstral Coefficients), and real-time compression algorithms with adjustable bit rates. The modular architecture allows easy integration of custom algorithms while maintaining optimized computational performance through vectorized MATLAB operations. For developers seeking a robust speech processing solution, this MATLAB toolbox represents an ideal choice with its comprehensive functionality and documented code examples.
