Abstract: Some basic concepts of speech recognition are introduced. And the course of dual threshold endpoint detection is detailedly introduced by flow chart. Continual HMM was used as model of system. The three basic problems met in the course of realizing system are analyzed and the corresponding solutions are provided. The accuracy can reach to 95% by using system which recognized different voice commands of different people. 

Key words: speech recognition, endpoint detection, HMM
