Development of a voice-control smart home environment

With the development of smart home technology, the living conditions of people have been improved greatly. However, the aged and the disabled people cannot operate the devices in the home flexibly, so we designed a smart home environment which is controlled by voice. The system can identify the speech signal even if someone else is speaking. At the same time, the system can change the state of lamp and curtain, and control the robot to grasp objects. This voice-computer interface system uses a microphone to collect speech signals, and MCU module uses a STC90C516RD+ MCU to control the lamp and curtain. Besides, this system uses object recognition technology to locate the target object. Finally, SR module can communicate with the central control program by socket. According to the tests, the success rate of system is 93.3%, which means that the system can achieve the intended target.
