Speed Recognition System of Smart Home

Abstract

The system provides a speed recognition system installed at the smart home. Any person could utilize the system to orally operate the TVs and lighting fittings. The system is composed of speed recognition TV dialing system, speed recognition living room-based lighting fitting system. The design achieves the intelligent control of home with the core STC89C52 single-chip computer, the LD3320 speech recognition module and infrared T-R module. The system functions with the hardware and by the software. When the LD3320 speech recognition module receives the user speech command, it would quickly collect and process this command, and then send the command to the single-chip computer of master control which would follow the set programme to analyze and process the command. The command which had been processed with the infrared T-R module would be sent to the single-chip computer which would process and reduce the speech command. The object to be controlled would be demanded by the command to alter real time the relevant display status. The tests prove that the design has an functional accuracy of 93%.
