Now-a-days we can find huge number of apartments crowded in nearby area with multi storage building capacity .The apartment consists of several floors. This project better suits for all, mainly for physically challenged people. To move from one floor to another we generally use staircase or Elevator which is normally operated by using switches. The main purpose of designing this project is to operate the Elevator by using voice commands.

 Elevator has to be moved vertically by recognizing our voice commands by using speech Recognition module. By giving different commands lift can be moved from one floor to another automatically. If voice command is received successfully by Elevator an acknowledge will be coming in the form of beep sound from buzzer. In this way activation of buzzer depends on the voice command received by Elevator.The project is built around AT89S52 microcontroller Voice Recognition module is interfaced with microcontroller to drive the Elevator. A 16X2 LCD display is used for the display of Elevator where it is currently placed and its status can be obtained.

This project uses regulated 5V, 1A power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
