Computer Based Test using Speech Recognition System

Abstract

Speech recognition system is a system that can converts audio signals into machine-readable format to provide interaction with the system. In this paper the speech recognition system is applied within the E –Learning system.  A headset microphone is interfaced to the computer system for speech production, a speech engine to help analyze each spoken text as programmed in the source code using XML format as the back end for stored text. This technique process data capturing more promptly than the existing process by keyboards or mouse, and can be used in working environment where these devices cannot be used and also for the disable learners that cannot use their hands or communicate through textual medium. Speech Recognition System is a developing technology and its application in this context is done within the Computer-Based Test as a pilot study.  The speech SDK (Software Development Kits) used has an inbuilt speech recognition engine and inbuilt simulator, the engine provides the speech recognizer that is able to recognize the user’s speech and integrate it with the inbuilt simulator.
