Today we can find a large number of crowded apartments in nearby areas with multiple storage capacity. The apartment consists of several floors. This project is best suited for everyone, mainly for people with physical disabilities. To move from one floor to another we usually use a staircase or elevator that is normally operated by the use of switches. The main objective of this project is to operate the elevator using the voice command.
The speech recognition system provides the communication mechanism between the user and the elevation control mechanism based on the microcontroller. This project uses a DC motor to move the elevator / elevator based on the voice / voice commands given by the user and the speech recognition chip is used to recognize the voice commands. The microcontroller is programmed, with the help of built-in C instructions. The microcontroller is able to communicate with all the input and output modules. The voice recognition system that is the input module to the microcontroller takes the voice instructions given by the user as input and the controller judges whether the instruction is to lift up or down and according to the voice of the user the switching mechanism controls the elevator . Similar voice-based commands are also used to activate / deactivate the fan inside the elevator. In addition, the LCD screen is available to obtain visual information of the operations that are being carried out.
