Outline of Final Research Achievements

We aimed to develop a method to continuous and quantitative evaluation of psychotherapy. (1) A database consisting of 44 sessions was developed with several kinds of annotations. (2) Active listening in psychotherapy was evaluated as time-sequential values by using a real-time, continuous input system. (3) Small sensors and integrated softwares were developed to measure speech and body movements. (4) The time-sequential values of active listening was analyzed qualitatively and quantitatively. It was checked whether they were predicted from feature vectors of speech sounds. They were also analyzed by multi-resolution wavelet analysis to detect the change points, which was found consistent between psychotherapists. Experiments were performed to compare evaluations on the change points between professional psychotherapists and undergraduate students. The method used in this experiment would be useful for education of psychotherapy.
