Speech Coding MATLAB Toolbox

This text introduces a highly efficient Speech Coding MATLAB Toolbox designed to facilitate advanced speech coding, compression, and recognition tasks. For speech coding enthusiasts or researchers working in related fields, this toolbox provides substantial support. The workflow involves importing audio files into the toolbox interface, followed by step-by-step operations that generate high-quality encoded outputs. The toolbox incorporates multiple algorithms and models, including Linear Predictive Coding (LPC), Code-Excited Linear Prediction (CELP), and Mel-Frequency Cepstral Coefficients (MFCC) implementations, allowing users to select optimal coding strategies based on specific requirements. Key functions include audio preprocessing, feature extraction, parameter quantization, and bitstream generation, with modular code structure enabling easy customization. We anticipate this toolbox will significantly advance your speech coding projects and contribute to your research development.
