基于语音信号的数字信号处理课程实验教学改革

The Reform of Experiment Teaching in Digital Signal Processing Course Based on Voice Signal

针对当前数字信号处理课程中存在的问题,探索对实验内容,实验环节设计以及实验考核方式的改革,通过引入语音信号为实验对象,增加一系列自主性实验内容,并重新设计实验环节与考核方式,从而形成一整套实验方案,以强化学生对数字信号处理理论的理解,掌握数字信号处理技术的应用,提高学习主动性,提升学习效果。

Focus on the problem of experiment teaching in Digital Signal Processing course, the reform including experiment content, experiment step and evaluation model was explored. The voice signal was introduced as experimental objective and experiment content was enhanced. The experiment step and evaluation model was re-designed for developing an experiment project. After comparing with traditional experiment teaching, it will increase the students＇ understanding and encourage study initiative on the Digital Signal Processing course.
