Application Of Cloud-Based Intelligent Voice Technology In Smart Home

With the development of science and technology in recent years,great achievements have been made in the Internet of Things,communications,big data,artificial intelligence,cloud technology,etc.,and smart home technology has gradually matured.The home appliances are connected to the network,and the home appliances can be controlled through the smart terminal,which brings great convenience to life.However,it is generally controlled through the app,and there are problems such as monotonous control and lack of experience.This design intends to use intelligent voice technology in smart home to make home life more intelligent.This system is composed of five parts: smart home equipment,Alibaba Cloud Io T cloud platform,Web server,Baidu intelligent voice cloud platform and voice terminal.The smart home device is developed using ESP8266 chip of Espressif.It writes the underlying code to achieve network access,completes the registration on the Io T cloud platform,and parses the data sent by the cloud to complete the control of peripheral devices.Io T platform,whose function is to manage and control the connected devices.The device and the Io T cloud platform exchange data based on the MQTT protocol;the Web server is developed using Spring Boot,and its function is mainly used to connect the Io T cloud platform and the intelligent voice cloud Platform,convert the request of the voice cloud platform into a request recognized by the Io T cloud platform and the feedback from the Io T cloud platform into a response recognized by the voice cloud platform;the function of the voice cloud platform is to recognize the received voice signal and then forward it to The web server is used to control the Internet of Things;the voice terminal program is developed based on the Android system.Its function is to receive the voice signal input by the user,send it to the voice cloud platform after preprocessing,and receive the processing result of the voice cloud platform and broadcast it.Through testing,this system can implement voice-based smart home control.Through the Web server,the capabilities of the voice cloud platform and the capabilities of the Io T cloud platform can be seamlessly connected,making it possible to quickly connect the voice recognition capability to the smart home.The entire system is stable in connectivity,easy to deploy,and low cost.The main functions are deployed in the cloud,and the scalability has been enhanced without major changes in hardware.It is a development direction in the future with broad prospects.
