VOICE ACTIVATED DOOR

Voice activated door is a voice input environment control unit for use by
individual. The system operates in response to voice command by converting the
sound input energy into electrical energy. This voice activated door opens when the
user gave command, "Open" through the speech recognition and it closes
automatically as the userpasses bythe door by stepping onthe touch plate (i.e. enters
the room). The objective of the project is to help disable person enters a room, place
or area with ease. This system also can provide a security system for entrance for
some area, by using different command password for each user. Thus, only
authorized person can enter the area. The designed voice activated door system
consists of 3 mains parts which are speech recognition for recognizing the input
sound, DC motor control circuit attach with the rack and pinion gear system to
control the door operation (close /open) and touch sensor as an object detection to
detect an object that enters the room, which then automatically closes the door. For
better operation of the system, electric strike and cylindrical locks are used for
locking system purpose, with fail secure mode. Fail secure mode will leave the door
lock if power failure occurs. This willavoid from unauthorized userto come in which
obeys the security objective. The voice activated door system produced is low in
cost, simple and capable in helping the disable people as well as enhances the
security system.
