According to the basic principle of HTK(HMM Toolkit),smal vocabulary continuous speech was recognized based on HTK by MatLab programming in this thesis.This thesis used HTK to build HMM model and then used MatLab to program it to do speech recognition,thus it avoided the redundancy of operating single HTK command,and the complexity was reduced.as wel .%本文根据HTK(HMM Toolkit)的基本原理，在MatLab环境下通过调用HTK各命令实现小词汇量连续语音识别。采用HTK工具包搭建语音的隐马尔可夫模型（HMM），再利用MatLab循环编程开发进行仿真实验，避免了传统地逐步运行HTK各个命令的冗余操作，降低了操作复杂度。
