语音信号处理实验教学研究探索

Research on the Experimental Teaching of Speech Signal Processing

针对语音信号处理课程实验教学的难点,以MATLAB软件作为平台,设计开发实验教学辅助软件,包括时域分析、频域分析、线性预测基音检测、语音编码、语音识别(DTW和HMM)、语音增强等知识,给学生以直观的认识,加快理解过程,增强学生解决问题的能力。

Aiming at the difficult points in the experimental teaching of speech signal processing, by using MATLAB software as a platform, this article designed and developed some experimental teaching aid systems, such as time-domain analysis, frequency-domain analysis, linear prediction, pitch detection, speech encoding, speech recognition （ DTW and HMM） and speech enhancement. That will give students a direct understanding and enhance their practical ability to solve problems.
