In Nigeria today, the adoption of computer-based Test (CBT) over the years has become an acceptable and ideal method for assessing student’s performance in the university system. However, since its introduction, candidates are only allowed to read questions from the computer screen and input answers via the mouse or keyboard without attending to the needs of the physically challenged who are vision impaired. Hence, this study proposed the design and implementation of a CBT with voice command. This study adopted the object oriented analysis and design methodology (OOADM). Python programming language and React.js, were used to implement the system, and supported with MangoDB database engine. The system is a web-based application based on behavior and states of objects. The voice mode is enabled with a click to read onscreen questions to the blind candidates, using the API.gTTS Google Text-to-Speech API with the aid of earpiece and system speaker
