Voice Stress Analyser System for E-testing

Three e-learning Master degree studies were introduced at Vilnius Gediminas Technical University in 1999. In order to increase the efficiency and quality of e-learning studies, Voice Stress Analyser Intelligent System for e-Testing (VSA-IST VSA-IST) was also developed. The aim of this paper is to report on the contribution of new integrated technologies (Voice Stress analysis and decision support systems) to e-Testing Systems. The article briefly describes the use of these integrated newest technologies in e-Testing. The authors of the article have developed a voice stress database, which contains students’ answers that are given during an Testing, and a specific algorithm, which is the core of the VSA-IST and which can evaluate a student’s knowledge by giving a precise mark after a psychological test, which is performed prior to the Testing. In order to demonstrate the validity, efficiency and usefulness of the developed VSA-IST, the article also presents a case study.
