MATLAB Program for Speech Analysis

This is a MATLAB program developed by the Department of Electrical Engineering at the University of Texas for speech analysis. The MATLAB software tool assists users in speech analysis research by providing a comprehensive suite of functions and utilities for detailed processing and examination of speech signals. Key functionalities include spectral analysis algorithms (such as FFT-based frequency domain transformation), feature extraction methods (like MFCC calculation and pitch detection), and speech recognition frameworks. The software implements DSP techniques including digital filtering, windowing functions, and time-frequency analysis through MATLAB's Signal Processing Toolbox. With its user-friendly interface built using MATLAB's GUI components, the tool simplifies complex operations while maintaining analytical precision. Overall, this MATLAB program serves as a robust platform for speech analysis experiments and research, incorporating both classical signal processing approaches and modern machine learning implementations for pattern recognition.
