In this paper, we propose a novel scheme for speech emotion recognition, which uses decision-templates ensemble algorithm (DT) to combine base classifiers built on segment-level feature sets. Different feature sets from segments can provide sufficient diversity among base classifiers, which is known as a necessary condition for improvement in ensemble performance. Compared with those methods of majority voting ensemble and support vector machine, our ensemble scheme can achieve the highest performance at suitable segment levels. On the other hand, we investigate which segment-level and strategy of training base classifiers can provide potential performance in speech emotion recognition, in terms of diversity analysis.
