The Application of Web Speech API for Controlling Electrical Appliances in the House via Mobile Phones with Android

Abstract

The application of Web Speed API for controlling home electrical devices via mobile phone with android OS has an objective in developing electrical devices control system through voice control application. The developed application was able to control a model demonstration house and its smart plug that used micro controller NodeMCU ESP8266 in order to control the application and to compile the command. This research was divided into 3 developing parts which consisted of 1) model house for overall demonstration 2) smart plug for demonstrating the application with real electrical devices and 3) application for controlling and assessing of the voice command. The performance testing was also divided into 3 parts which included 1) ambient sound assessing which affected the voice command. The result indicated that with an ambient sound between 0 to 60 decibels, the application was able to perform at 100 percent accuracy but with an ambient sound at 70 decibels onward, the application was unable to perform. 2) application testing with electrical devices inside a model demonstration house and 3) application testing with electrical devices that connected to a smart plug with a controlled ambient sound not more than 60 decibel founded that the researcher was correctly able to control a model house and its electrical devices that connected to a smart plug as specified. Therefore, the application of Web Speed API for controlling home electrical devices via mobile phone with android OS can control electrical devices using long-distance voice control through android application and able to control home electrical devices.
