Abstract
Computer-based education systems utilizing adaptive teaching strategies could benefit greatly from a knowledge of the student-user's emotional state. Comparative studies of speech analysis techniques suitable for a two-way audio communications system between student and computer led to the hypothesis that voice pitch frequency is related to emotional state. Experimental results are given based on the analysis of words spoken by drama students, which validate this hypothesis, and recommendations are made for incorporating a two-way audio component into future computer-based learning systems.Keywords
