The device controlled by a switch or remote is the old concept now. The next-generation technology is here. The “Voice Operated Home Appliance Control System” project utilizes human voice command to control electrical devices. The user has to give voice commands to an Android application. This application recognizes the voice commands and sends them to the Voice operated device controlling project. A receiver and decoder decode these commands and give them to the 8051 microcontroller over a serial port. Then the microcontroller takes a decision on which devices to control depending upon input received from the Android application.
Device control with voice is one of the main areas of future research. Imagine a world where users can do each and every task by just talking. We have already seen a few automobile industries have implemented this in cars. Voice Controlled Home Appliances have many applications including device controlling inside the home as well as in industry. So basically we are going to Control home appliances using voice-based commands.
Talking about voice-operated device controlling, we can say that roughly there are two types of controlling operations. In the first one, the user has to speak in a microphone connected to the electronic circuit. And in another type user can speak on an Android mobile or any other device and then this device sends commands to the project through a wireless communication technique. In this project, we have used a second type of operation, which means voice control through an Android mobile application. One of the primary purposes of this technique is to reduce human efforts. Users don’t have to get up from their places to control the device. This is an advanced Voice Operated Home Appliance Control System that needs an Android smartphone or tablet. Voice recognition technology is used inside the Android app. We can control devices by using our voices. This project really proves useful for physically disabled people or senior citizens or elderly people at hour homes or even those people who are injured and can not walk or move.
You will get the following documents with this project:
Various important blocks of the system are:
There are many Applications of Electrical Appliances Control By Human Voice, few of them are listed below:
Advantages of Speech Operated Home Appliance Control System:
YouTube video coming soon. The video for this project is not available right now, we are planning to upload a video soon. Meanwhile, you can watch a video of another project in the category of Android-based projects.
Question: Which wireless technology is used?
Answer : Bluetooth technology. So we can say that this is Remotely operated home appliances using voice commands using wireless communication.

How to use this?? Whether we hav to connect these thing to the device we are going to control? How does it work ? Is it just for switching on/off the device ?
I need to know about decoders? Can yu please help me to understand clearly ? What is the purpose of using decoder here ?
for which type of home appliances it will be working?
What is the frequency of the sound? We have send to the our android phone to the Bluetooth receiver.
