Design and implementation of JAMB Computer-Based Test System with Voice Command

Abstract

This work was motivated by the desire to develop a Joint Admission and Matriculation Board (JAMB) Computer Based Test (CBT) system for the physically challenged. Since JAMB introduced a computer based software, examination candidates are only allowed to read questions from the computer screen and input answers to the questions via the mouse or keyboard. This computer based test software came with some challenges especially for candidates who are physically challenged. These candidates do not find it easy to read from the computer screen and or make input through the keyboard. Hence the design and implementation a JAMB CBT with voice command was embarked on. Object oriented analysis and design methodology (OOADM) was adopted in this study. Microsoft Visual Basic.NET was used to implement the system. This was supported with MySQL database, a free distributed database engine. The system is a desktop application based on behavior and states of objects. The system reads onscreen questions to candidates, using the earpiece and allows candidates most especially the physically challenged to make input or control the system using voice.
