摘　　要：针对“新工科”对学生的工程应用能力和综合素质提出更高要求的背景下,开发了基于MatlabGUI的语音信号处理虚拟仿真实验平台。该平台可实时录制本人语音信号,并可根据男女声分别进行时域处理、频域处理,声音特殊效果的处理等,通过对比男女声的时频特征,及滤波处理和变声处理的前后变化,加深学生对语音信号处理的体验,提升工程意识和思维能力。In the context of "new engineering" putting forward higher requirements on students’ engineering application ability and comprehensive quality, a virtual simulation experiment platform for speech signal processing based on Matlab GUI was developed. The platform can record the voice signal of the person in real time, and can perform time domain processing, frequency domain processing,sound special effect processing, etc. according to the male and female voices respectively, and deepen students’ experience in speech signal processing and enhance engineering awareness and thinking ability by comparing the time-frequency characteristics of the male and female voices and the changes before and after filter processing and sound processing.
