IEEE PROJECT TITLE&ABSTRACT FOR ECE/EEE-Wireless voice controlled household device activation and control system

  1. 1. RF Based Wireless Voice Controlled Household device activation and control system This project is designed to control the home appliances through voice (on/off) control as dictated by the person “Switch on Fan”, Switch Off Light” etc. The Voice Recognition involves HM2007 IC which is dedicated to process the voice inputs. The voice inputs is processed by HM2007 IC and the outputs are given through Wireless using an Encoder. Another unit is used to decode the wireless inputs and send it to the appropriate devices for controlling. Master Controller: MAASTECH,89. Rangarajapuram main road,(Near SBI Bank) Kodambakkam,Chennai-600024, http://www.maastechindia.com
  2. 2. A pic Micro controller will act as a master controller for the switching of devices. Voice Controller: A voice said in front of the mic is converted to text by the Voice Recognition IC HM2007 and is fed as a input to the controller, so the controller reacts to it. Software Driver in Hitech C This is a software tool used to control the angular position i.e., to send specified pulses with controlled timing to vary the speed as when and where required.
