MATLAB Code Implementation for Speech Signal Analysis

This MATLAB source code collection provides comprehensive tools for speech signal analysis, including harmonic analysis, intensity analysis, and voice source analysis. The software package contains a series of MATLAB routines specifically designed for various aspects of prosodic analysis in speech processing. Key functionalities include F0 detection using autocorrelation or cepstral methods, harmonic analysis through spectral peak tracking, loudness calculation based on psychoacoustic models, and voice-source analysis employing linear predictive coding (LPC) and inverse filtering techniques. These routines implement advanced digital signal processing algorithms that enable researchers to perform in-depth speech analysis, generate quantitative data, and extract meaningful parameters to support acoustic research and speech processing applications. The codebase features modular functions for signal preprocessing, feature extraction, and visualization, allowing for flexible integration into larger speech analysis pipelines.
