The main objective of this project is to design and build a voice-operated lift / elevator control system. This system acts as a man-machine communication system. Speaks Recognition is the process of recognising spoken words to take the necessary actions in consequence. The user can also control electrical devices like fan, door etc. with the help of Voice recognition system. This device is very useful for paralysis, people of short height And people with physical disabilities. The voice recognition system provides the communication mechanism between The user and micro-controller based lift control mechanism. This project uses A DC motor to move the elevator / elevator based on the voice / voice commands given by The user and voice recognition chip is used for recognition of voice commands. The micro-controller is programmed with the help of built-in C instructions. the Micro-controller is able to communicate with all input and output modules. the Voice recognition system which is the input module for the micro-controller takes voice Instructions given by the user as input and the controller judges whether the instruction is To lift up or down, and in accordance with the voice of users switching Control the elevator. Similar voice-based commands are also used to enable / disable The fan inside the elevator. Also, LCD display is available for visual information of operations What is being done.
