e-learning system with a confidence evaluation through voice response analysis

An e-learning system with a confidence evaluation through voice response analysis is proposed. The system does care about the confidence level of the students when the students respond to the questions raised from the systems through human voice analysis. Otherwise, the students et a trouble as they pass step-by-step based exercises without confidence. So that the proposed system evaluates their confidence during exercises with human voice analysis, how do they feel. Through experiments with 10 of students, it is found that the proposed system achieved 10% improvement of the final achievement test result in comparison to the system without confidence evaluation.
