title: Affective state and voice: results of a pilot study with six depressive patients.
abstract: As part of an investigation into the nonverbal information in human speech, a pilot study with depressive patients was designed in order to model the global affective state as a function of time and in terms of speech parameters. Over a two-week period, six patients were examined six times at two-day intervals under comparable experimental conditions. The psychopathologic status of these patients was assessed during a psychiatric exploration half an hour before the actual examination was carried out. Besides the solution of the baisc methodological problems, a principal goal of this study was to test the ability and cooperation of depressive patients when asked to speak in the laboratory. It turned out that even scalar parameters such as energy and dynamics give insight into the intraindividual variation of global affective state, and that the examination procedure is practicable even it patients are considerably handicapped by their illness.
