ABSTRACT: The most crucial form of human communication is speech signals. Almost all encounters use speech signals in conversations. With a microphone, sounds and different speech signals can be transformed into electrical form. Physical disability can result from a variety of causes, such as age-related issues, health issues, and accident-related injuries. For these challenged individuals who suffer from impairments in their hands and legs, vehicles are used as a means of transportation. It might be challenging for anyone with certain conditions, such as paralysis, to manually push a wheelchair or use a remote assembly. For these individuals, the project is made to work with voice-based commands, enabling the paralyzed or impaired person to offer directions simply by speaking into the provided microphone. Additionally, the device has directional buttons for remote vehicle control. An Atmega328-based circuit interfaced with a voice recognition module builds up the system. The voice recognition module receives user commands and translates them into digital data, which the micro-controller analyzes to obtain directional orders. The transmitter circuit and the receiver circuit make up the whole system. The voice recognition module is part of the transmitter circuit, and the motor and driver assembly are part of the one that receives circuit. For communication, an NRF trans-receiver module is used. The command issued to the vehicle is shown on a 16*2 LCD.
