The study aims at to provide convenience and assistance for the mobility of the disabled or elderly home life, so that they can through speech recognition system of household electrical appliances, lighting systems, door and window switch to realize intelligent control. By looking up the information, the information of the parameters, the price and the rate of recognition, the LD3320 based speech recognition system is used to control the home circuit. System consists of four parts, namely: YS-LD speech recognition module, STM32 microcontroller control unit, LED display unit, relay output unit. LD3320 speech recognition chip - based on the STM32 microcontroller operation analysis - a signal . After testing, the system of speech recognition rate is as high as 90%, without requiring the user to create their own speech model and the development of speech recognition algorithm, the lower the threshold of the development and application of technology, is conducive to the promotion and application.
