VOICE-ACTIVATED REMOTE CONTROL FOR FAN/HEATER

The objective of this project is to activate the old version of remote control, used for
home electrical appliances by human voice instead of operating manually. This is
intended with a view to provide more comfort for the human community. A variety of
remote controls available in market today are made to function by pushing the buttons
manually in order to have required changes in the electrical device such as increasing or
decreasing temperature. Technological advancements in the society have made people to
look for the easiest and novel ways to respond to their needs. In addition to this, some old
and/or disabled people have difficulties in doing their work with out others help.
Successful implementation of this project in the practical device will provide opportunity
to people who are tired enough to look for the remote control ,old and/or disabled people
who can not walk or have problems working with their hands, to interact with the remote
control through their voice commands. This type of remote control triggered by human
voice will be realized through the use of a microcontroller and a multipurpose voice
recognizing IC (HM2007) to get the user command and compare it with the prerecorded
voices on the IC HM2007. Upon voice comparison, the microcontroller will choose
appropriate button to be pushed according to the requirement of the user, and the user
command will be executed. The successful out come of this project will be a useful voice
activated remote control which can be exploited with regard to the electrical appliances.
