虚拟实验在"语音信号处理"课程教学中的应用

利用软件技术构建虚拟实验是提高计算机教学及实验效率、降低实验成本的一条有效途径。本文介绍虚拟实验在语音信号处理中的应用，可以使学生在自己的PC机上完成各种语音信号处理实验，并对实验过程中出现的问题进行相应的指导，从而可以有效的缓解学生数量的日益增多与实验设备不足之间的矛盾。在语音信号虚拟实验设计过程中主要采用MATLAB来实现，并给出了利用MATLAB实现语音信号处理的例子。针对本科生语音信号处理课程学时少而内容多的特点，为提高教学质量对语音信号处理课程的教学内容进行改革。

Application of Virtual Experiment in Teaching of Speech Signal Processing

Building virtual experiment by software techniques is an efficient way to improve the efficiency of computer teaching and experiment design. The application of virtual experiments in the teaching of speech signal processing is introduced in this paper, which is proposed to resolve the contradiction between increasingly increased student number and the insufficient experimental equipments. The students can complete their experiments using their own PC. Virtual experiments are designed by MATLAB, and some examples are given in this paper. Aiming at enhance the teaching quality, the content of speech processing is adjusted accordingly.
