Abstract

            A voice-Activated phone was designed for an elderly woman with limited vision and moderate arthritis.  Voice commands allow the user of this phone to place calls without the need to look-up phone numbers or press buttons, however, the phone can still be used as a normal telephone.  This device makes life easier because voice commands do the work for dialing a phone number.

            The voice-activated phone consists of three parts: a voice recognition circuit, a telephone, and a dialing circuit.  The voice recognition circuit is based on the HM2007 voice recognition chip. The HM2007 selects the proper voice command number from the RAM and passes it to the microcontroller. After receiving the stored word number, the microcontroller responds by “dialing” phone number associated with the voice command number.
