Project: Home Applinces Control By Human Voice

We can control any home appliances by using our voice. The main aim of this project is to control light, fan, computer etc... by using human voice. The physically handicap people does not capable to operate home appliances by using their hands. They are not capable to on/off the switch by using their hands since This project is very useful for physically disabled/physically handicap person .They are capable to  operate home appliances by using their Voice. In this system we are using voice recognition module to recognize their voice.  When we speak one than first device will be on and remaining devices will be off. When we speak two than second device will be on and remaining devices off and so on. 
Voice Controlled Home Appliances
In the normal switch board we have to push switch manually and oftenly stand up and operate switch manually so that it is wasted of time, It is also used to operate for handicap person, using a voice recognition application which is interfaced with electric device. The prototype of the Switchboard is built using a micro-controller, chosen for its  low cost, in addition to its versatility and performance in mathematical operations and communication with other electronic devices. The system has been designed and implemented in a cost effective way so that if our project is commercialized the needy users in developing countries will benefit from it   
·        Technology used in our project:
Here we are using voice reorganization technology. So we are using HM 2007module to recognize the speech signal. This module is used to convert the voice signal into corresponding binary code that is given to the microcontroller, and the microcontroller gives the output according to the voice input.
Generally microcontroller generates codes in its output according to the input. So using this module we can control switch relay corresponding to the voice command.
·         Here there are five voice command is used for controlling the switch relay
1.      Switch1
2.      Switch2
3.      Switch3
4.      Switch4
5.      Switch5
6.      Switch6
·        Working with block diagram, circuit and PCB:

 Advantages:
  • Compact
  • User friendly
  • Less complex
  • Low cost
  • Easy to implement
  • Accuracy
  • Economical
  • Reduce manpower
Application of voice controlled Switchboard:
·        This is useful in communication equipment to prevent the signals or noise coming from the speaker.
·         switch a device  used in such as a computer or appliance or lamp on and off by voice command or other sound.
  • In telephone communication.
