A GENERAL SPEECH SIGNAL ANALYSIS WORKSTATION

Designing and realizing a fast,converient and practical system used for general speech signals analysis is an urgent problem in speech teaching and research.A new systemfor digital speech signals analysis is introduced.It includes functions from speech signal A/Dand D/A to the extraction and analysis of typical characteristic parameters often used in timeand frequency domain,especially the new three--dimension dynamic spectrum. Based on a personal computer,with the addition of a diskette of 1.ZMB and a interface board for speech inputand output,all of the parameters can be extracted and analysed quickly in the company withmany graphs. In order to help different users,the system has adopted Chinese as prompt. Theresult shows that it is general and practical
