Abstract

            The voice activated speakerphone was designed to help enable clients who can not lift their arms or move their hands but still have a strong voice to pick up phone calls and make telephone calls using voice commands.  The project simply modifies an existing telephone and interfaces it with a voice recognition circuit to enable usage.   

            The project consists a voice recognition system (HM2007 VR chip) and a microcontroller (Basic Stamp 2e).  The HM2007 VR chip can recognize 20 to 40 programmed words. Basic Stamp 2e is used to switch on and off the speakerphone and also dial phone numbers.  When given a voice command, the HM2007 will send high or low signals to the Basic Stamp 2e to perform a specific instruction.
