Based On The Research And Development Of Android Smart Home Voice Interaction System

This paper studies the smart home voice interactive system,applies the offline voice recognition technology to the smart home voice interactive system,and integrates the traditional home appliances into the control system,so that the smart home interaction system can not only control smart home appliances,but also Control of traditional home appliances can be achieved.The main research contents of this thesis are as follows: The directional picking of voice commands is analyzed in detail,and then the Dynamic Time Warping(DTW)speech recognition algorithm in offline state is introduced in detail.The deficiencies of the search range of the template matching path in the dynamic time warping algorithm are improved.The improved DTW speech recognition algorithm has further limited range of template matching paths,which makes speech recognition faster,has lower distortion,and has higher speech recognition efficiency.The voice control smart device cannot be separated from the cloud.This paper designs a cloud platform suitable for the system of the smart home interaction.The addition and management of devices and scenarios can be implemented in the cloud platform.The cloud reads the working status of the home appliance in real time and changes the working status according to the user's instruction.The design and implementation of the control terminal include Android software development design and hardware selection,design and construction.Android software design corresponding control interface.The control terminal hardware module is designed with infrared and radio frequency learning and transmitting modules,and can learn the coding mode of the traditional home appliance remote controller.System testing in both online and offline situations,users can send commands through the control terminal or the cloud smoothly,and the home appliance can accurately respond it according to the instructions.
