DESIGNING AND MANUFACTURING A VOICE CONTROL SWITCHING SYSTEM OF ELECTRICAL DEVICES (Pages : 23 - 27)

A voice controlled remote switch for various electronic appliances has been modeled, constructed and tested in this project. For voice recognition, SAPI software is used and for recognition engine recognizes the voice of a user and converts it to the signal, which passes through the printer port. A circuit is developed to convert this signal into Infrared (IR) signal. A receiver circuit is developed to receive the Infrared (IR) signal and conduct switching according to the signal. Because of converting the voice signal into Infrared (IR) signal and developing of a Infrared (IR) signal receiver, the electronic devices can operate by voice as well as IR remote from a remote place. So it may be designated as a complete remote control system. Eight voice instructions such as fan-on, fan-off, one, two, three, four, start & stop have been made for operation of the switch. The whole system acts upon this instructions and conducts the corresponding switching action for each instruction.Download
