transforming mere words into actions. By harnessing the capability of the human voice, voice-controlled wheelchairs offer a hands-free approach to wheelchair operation, liberating users from the constraints of traditional joystick or lever controls. Mobility is a fundamental human right, and it is essential to guarantee that individuals with restricted mobility have the means to move around independently. In this context, the development of supportive technologies like wheelchairs plays a vital role in enhancing the quality of life for individuals with disabilities. The project seeks to design and develop a Voice Controlled Wheelchair to provide individuals who have limitations in mobility a more accessible and user-friendly means of controlling their wheelchairs. In an ever-evolving world of technological advancements, the field of assistive technology has arose as a beacon of hope for enhancing the lives of people with physical disabilities. Among these innovations, the VoiceBased Wheelchair Project stands as a remarkable endeavor aimed at revolutionizing mobility and self-reliance for individuals with restricted motor control. For those whose mobility is compromised due to situations like paralysis, muscular dystrophy, or cerebral palsy, the ability to manage a wheelchair with voice commands represents a significant leap towards I II regaining autonomy and freedom. This project harnesses the power of cutting-edge voice recognition technology, enabling users to navigate their wheelchairs effortlessly by simply vocalizing their intentions.

1.INTRODUCTION

2. LITERATURE REVIEW

A voice-controlled wheelchair is a wheelchair with controllable features using voice commands. This is a valuable technology designed for individuals with disabilities who experience challenges with manual dexterity or arms to operate traditional wheelchair. Voice-controlled wheelchairs have emerged as a revolutionary assistive technology, empowering individuals with disabilities in order to regain control over their mobility. These wheelchairs make use of speech recognition technology in order to interpret and execute voice commands,

[1] The historical development of automated wheelchairs, highlighting the proposed voice-controlled design's simplicity and affordability. It explains how voice commands are processed and translated into motor movements using Arduino Mega. Additionally, ultrasonic sonar sensors and a gyro-accelerometer are integrated for obstacle detection and stability. Research presents a promising, accessible, and cost-effective approach to voice controlled automated wheelchairs, benefiting a broader user base, especially in developing countries.

Control System for motorized wheelchairs, transforming individual accessibility with mobility impairments. The integrated system leverages advanced technologies such as natural language processing, speech recognition, and hardware integration to allow users to effortlessly command wheelchair movements through natural speech. Managed through a user-friendly Android application, the Voice Controlled Wheelchair System responds to intuitive voice commands for providing a smooth and accessible means of mobility. The technology prioritizes user-friendliness and efficiency, ensuring a user-centric and an inclusive environment for people who varying technical expertise. Via the assimilation of essential hardware components, including sensors and the HC-05 Bluetooth module, the system guarantees efficient voice command recognition and safe wheelchair operation. With a remarkable response time of mere seconds, both systems hold the promise of enhancing independence and mobility for individuals facing motor challenges. This innovative assistive technology represents a significant leap forward within the domain, offering a novel and inclusive approach to wheelchair mobility. The presented Speech-Based Control System participate in a more accessible and empowering future for people with motor disabilities.
