In this paper, a voice controlled home automation system based on a wireless network protocol known as Zigbee was applied in achieving a smart home. The design was accomplished using the HM2007 voice recognition chip and 8051 microcontroller kit and relays. Simulations were carried out using Proteus 8 and the programming of the microcontroller using C++. The system was initially in standby mode waiting for an input from the user and once an input is detected, it is analyzed by the speech recognition module. If a known command is detected, the speech recognition system sends respective digital representations to the microcontroller. The microcontroller then interprets these data signals, compares them with a database of stored commands and thus identifies the referred load and its desired state. The processing results are then displayed on the LCD which is primarily used to display the system states. Based on the load state identified, control signals are sent to respective relay circuits, thus actuating the appropriate loads. The simulation results showed that the voice amplitude was directly proportional to the load supply current while at a constant amplitude of 10Volts, the frequency varied between 900Hz and 1200Hz.
