摘　　要：MATLAB在数字语音处理方面功能强大,利用MATLAB软件解决数字语音课程教学中存在的难点,通过对时域、频域及二者相结合的过程进行分析,构建将理论结果可视化和基本概念直观化相结合的多媒体课程教学模式。MATLAB在语音课程教学中的实现过程,首先是将数字语音读取,查看其波形图。其次是录入数字语音并保存。最后经过对数字语音的滤波、叠加、预处理等过程,实现对数字语音的分析和重构。逐步改变了教学方法和教学手段,从而达到培养学生的学习兴趣和操作能力的目的。As a powerful tool in digital speech processing,MATLAB can be used to solve many problems appeared in digital speech course teaching.Through the analysis of time domain,frequency domain and the process of combining both,a multimedia course instruction model is constructed based on the combination of visualizations of both theoretical results and basic concepts.In the course of the digital speech course teaching,the digital speech is read and the waveform graph is checked in the first place.Secondly,the digital speech is input and saved.At last,the analysis and reconstruction of digital speech is realized after the process of the filtering,superposition and pretreatment of the digital speech.Through the improved teaching method and teaching means,the students＇ learning interest and operation ability are cultured.
