Control Devices by Voice Recognition

This post will serve questions like, How to control devices by voice commands , speech recognition available in android.


All the android devices comes with the inbuilt speech recognition. This can be used to convert speech to text, by calling bluetooth function these text can be sent to device in this case the text were transferred to an arduino. The app can made with ease in MIT app inventor Without any experience in programming. 

In the first video , I created a app for converting speech to text.


This app can be used for controlling any device, like robots or your electrical appliances, Lets see how to control electrical appliances by voice control. arduino pre-programmed to execute certain function if matches with some text. 



you can control any number devices by using this app. for arduino program Please refer to this page change the command whatever that is convenient for you.

refer the video below to know how to interface arduino to electrical devices.


check this link here to know how to create a voice controlled robot.





If you are looking to control devices by your voice, this is the best post for you. MIT app inventor provides space to make android app by building blocks. you can control all your gadgets robots and this app will be perfect for your home automation and control projects.

    1. If you want to control a robot , its recommended to use l293d instead of uln. As the circuit become complicated when we try to move in forward and reverse directions. Yeah you can use uln to l293d
