摘　　要：本文将MATLAB语言引入语音信号处理教学中,以基音周期估计和端点检测为例,阐述了利用MATL AB语言编程的编程思想、程序的编写及实现。将语音信号处理过程编程开发成可执行的程序,生成可以执行的动画文件。可根据实际的分析需要改变其参数观察变化过程,有助于将语音信号处理中抽象的概念形象化,促进学生对其理论的深刻理解。This paper adopts MATLAB software in teaching of the course of speech signal processing, introduces the design consideration and animation of the pitch detection and endpoint detection, and develops the speech processing into executive program. The series visual waveforms, which obtained by executing the program, can simulate the speech signal processing. Animation can help to visualize the abstract concept and get easy understanding of speech signal processing theory.
