Approach Towards Voice Control Smart Lift System for Physically Disable Person Using FPGA

Abstract

In every high-rise building lift has become an important part. Generally, all lifts are operated using switches. For physically challenged person or blind reach, their floor without aid is quite difficult.Speech is the main medium for human communication. The project represents the voice operated intelligent lift. This follows the principle of speech recognition. Lift is controlled by the user’s voice commands and useful for paralyzed, blind and physically challenged people. Lift operates based on the input voice commands, eliminates the use of buttons in the lift, and is user friendly. The project behaves like the human-machine interaction system and will be highly beneficial for the society. When user gives a command then voice recognition is done using Voice module and IR (infrared) sensor is used for detecting the floors, also stopping the motor rotation. The DC motor is used for controlling lift upward and downward motion. The voice-controlled lift is an implementation of FSM model in VHDL. The controller or the heart of this project is FPGA (Spartan 3a).
