In order to overcome the insufficiency of voice processing tool box in Matlab,a speaker recognition test platform based on graphic user interface(GUI)in Matlab was designed. In the system framework design,Mel?Frequency Cepstral Coeffi?cient and difference Mel?Frequency Cepstral Coefficient were adopted for feature parameters,and vector quantization model was adopted for recognition model. In implementation of human?computer interaction,the CheckBoxs’attribute was set,and system functions were achieved with callback function. 50 persons had been tested,and the recognition ratio is 96%. The result shows the validity of the test platform. The platform has the features of complete function,parameter regularity,such as number of peo?ple,number of words,frame length and so on. It is convenient for the clients to test and has very good applicability and interac?tivity.
