Abstract:With the remarkable improvement of people’s income and living standard,an increasing number of smart automation is coming into people’s life. At present,the mobile terminal system controls the smart home devices with a diversified and graphical smart home interface,which is favored by people. In order to further liberate people’s hands and make people operate smart home more easily,a smart home control system based on speech recognition technology is designed. Based on STM32,the system uses Mel frequency cepstrum coefficient(MFCC) algorithm and dynamic time warping(DTW) algorithm to analyze and recognize speech signals. Through ZigBee self-organizing network,the system collects indoor temperature,humidity,light intensity and other information,and controls the switches of intelligent devices such as lights,fans and curtains.

Keywords:speech recognition;smart home;MFCC;DTW;STM32;ZigBee
