在语音信号处理教学中引入仿真实验,通过上机实验帮助学生理解课程的基本原理和方法.课题组完成了课程系列实验的设计,分为验证型实验和设计型实验两种.主要以线性预测编码、复倒谱和倒谱以及感知线性参数等为例介绍了使用Matlab进行教学辅助实验的情况.
Simulation experiments were introduced to the teaching of speech signal processing experiments in this article,which help students understand the fundamental principle and methods in the course.A series of experimental design classified in to two types:replication experiment and design experiment were accomplished.Matlab assited teaching experiments,such as Linear Predict Coding,Complex cepstrum and cepstrum,as well as perceptual linear prediction were mainly discussed.
