This program designs and implements a basic speaker recognition system using MATLAB. Key functional modules include speech signal input management, feature extraction for speech discrimination, and speaker authentication. The system utilizes MFCC (Mel-Frequency Cepstral Coefficients) for feature extraction and GMM (Gaussian Mixture Models) for pattern matching, providing a comprehensive solution with additional modules for error handling and user interface.

Implementation of LBG algorithm for speech signal vector quantization. This package contains two main scripts: training.m processes training data to generate four initial codebooks using iterative splitting methodology, while quantizing.m performs vector quantization on target data through nearest-neighbor codevector matching. Additional custom functions support codebook initialization, distortion calculation, and quantization error analysis.
