语音信号处理实验的改革与实践

Reform and Practice of Speech Signal Processing Experiments

随着数字信号处理的发展,语音信号领域越来越受到关注,语音信号处理是实现人机交互和通讯技术的必要方法。语音信号处理教学实验课程在国外著名大学已经得到广泛开设。本文介绍了一门最新开设的将基础知识与理论研究相结合的语音信号处理实验课程。该课程主要由一系列由浅入深的语音信号处理实验构成,通过这些实验,使学生深入理解语音信号领域的前沿知识。在自主实验环节,学生自主提出实验题目及内容,通过小组形式完整地完成一个项目的设计、开发和汇报过程。本文将一个小组的语音分离项目为例,来说明该课程不仅能够培养学生的动手和分析解决问题能力,并能激发学生对相关领域的研究兴趣。

With the development of digital signal processing, speech signal attracts more and more attention, and speech signal processing is the necessary method of achieving human-computer interaction and communication technology. Speech signal processing teaching experimental courses in prestigious universities abroad have been widely opened. This article describes a newly opened course of basic knowledge and theoretical study of the combination of speech signal processing experiments. The course is mainly constituted by a series of speech signal processing experiments. Through these experiments students will be deeply understanding the frontiers of the speech signal field in independent labs. The students propose experimental subject and content. The experiments are developed and completed by student groups. This article will take a set of voice music separation projects as an example to illustrate that the course will not only be able to train the students hands-on and analytical problem-solving ability, but also can greatly stimulate students＇interest in related areas of research. This course has the great significance in deeply learning of speech signal processing courses and developing high-level talents in the field.
