摘　　要：为提升数字语音处理实验课程的教学效果,在项目驱动教学模式下,提出了研究性实验教学设计,以解决当前数字语音处理课程中实验教学只注重基础知识而忽略高阶知识,只注重书本而忽略创新的缺点。现以“声纹识别系统”为例设计了研究性实验教学方案。该方案取自于企业项目,包含了声纹特征提取和声纹识别两个方面,将语音分析和语音处理两个模块有机地结合起来。实验过程的实施不仅能够反映出学生对基础知识的掌握程度,同时还能提升学生的兴趣,激发主观能动性,培养创新意识以及提高解决工程问题的能力。In order to improve the experimental teaching effect of digital speech processing,a research-oriented experimental teaching design is proposed to solve the shortcomings of existing experimental teaching in digital speech processing course,which only pays attention to basic knowledge and ignores high-level knowledge,and only pays attention to textbooks and ignores innovation.Taking“voiceprint recognition system”as an example,this paper designs a research-oriented experimental teaching scheme.The scheme is taken from an enterprise project,includes voiceprint feature extraction and voiceprint recognition,and organically combines the two modules of speech analysis and speech processing.The implementation of the whole content can not only reflect students’mastery of basic knowledge,but also enhance students’interest,stimulate subjective initiative,cultivate innovative consciousness and improve their ability to solve engineering problems.
