Speaker recognition is the task of validating individual s identity using invariant features extracted from their voices print. Speaker recognition technology common applications include authentication, surveillance and forensic applications. This Paper investigates the performance of three automatic model selections based on Gaussian Mixture Model (GMM). These approaches are Bayesian information criterion (BIC), Bayesian Ying–Yang harmony empirical learning criterion (BYY-HEC) and Bayesian Ying–Yang harmony data smoothing learning criterion (BYY-HDS). Experimental evaluation of these methods is presented.

是《MATLAB数字信号处理与应用》一书的源代码,该书由李正周编著 清华大学出版社出版 2008年5月 本书主要介绍基于MATLAB R2006a的信号分析与处理的原理和应用。全书共分为7章：第1章对MATLAB R2006a的特点与MATALB的基本使用进行了介绍，第2章～第7章分别讲述了MATLAB中信号处理工具、MATLAB离散时间系统与Z变换、数字滤波器及其设计、平稳随机信号分析、非平稳信号分析与处理以及自适应信号分析与处理，并且每一章节都较详细地分析了包括雷达信号、图像信号和语音信号等信号处理综合应用实例。 本书可作为高等学校数字信号处理等课程的教材或参考书，对于从事信号处理及相关领域的工程技术人员也具有重要的参考价值。(err)

自己编写的55行精短情诗代码，呈现红色背景、白窗心形图案及动态U型符号，释义“Need you !”，码农也能文艺！(55 lines fine short poems codes, showing heart-shaped background and dynamic symbol-U,meaning "Need you!")

计算阶跃响应相关指标，包括超调量、上升时间、调整时间、稳态误差等，计算效果很好。( Calculate the step response-related indicators, including the overshoot, rise time, settling time, steady-state error, etc., is calculated with good results.)
