Abstract: AMOGUIS, JENINA R. and LINGON, MABEL A. Development of a Voice Controlled Wheelchair for Physically Impaired Individuals. Undergraduate Design Project. Bachelor of Science in Electronics and Communications Engineering. Cavite State University, Indang, Cavite. June 2016. Adviser: Engr. Edwin R. Arboleda. The general objective of this study was to develop a voice controlled wheelchair for physically impaired individuals. Specifically, it aimed to design and construct a voice controlled wheelchair. It also aimed to modify a standard wheelchair where the EasyVR 3 Voice Recognition Module, ultrasonic sensors, microcontroller, and 12V wiper motor were integrated. Moreover, it aimed to develop a program for the device and test and evaluate the design project. The design project was composed of a Gizduino 4.1 which serves as the microcontroller unit, EasyVR 3 voice recognition shield that was used to store and analyze voice commands, and a motor driver that drives and controls the wipers motors. The microcontroller gives the output signal to the motor driving circuit. Based on the signal given by the motor driving circuit, the controller switches the motor accordingly. The added safety feature is the ultrasonic sensor that senses obstacle with fall detection system and sends a signal to microcontroller to stop the chair. The unit was tested by the researchers. The project testing was done on Engineering Science (ES) Building, College of Engineering and Information Technology ( C E l T), Cavite State University (CvSU), Indang, Cavite. The perfomance between the speaker independent and speaker dependent features were tested in a noisy environment wh ere a lot of students are present Its responsiveness was also compared when there is no noise. The wheelchair was used by participants and evaluated it according to certain parameters. Based on the results of the evaluation, the project met the given objectives. The system was able to move in accordance to the voice command given. The device was also able to prove its functionality, responsiveness, usability, correctness, control, reliability, safety, and comfortablity. Technical evaluation showed that the device was not able to function correctly when a considerable amount of noise is present since this distorts the signal processed by the EasyVR shield
