ABSTRACT:
An apparatus for determining emotional arousal of a subject by speech analysis, and an associated method. In the method, a speech sample is obtained, the speech sample is pre-processed into silent and active speech segments and the active speech segments are divided into strings of equal length blocks (the blocks having primary speech parameters including pitch and amplitude parameters), a plurality of selected secondary speech parameters indicative of characteristics of equal-pitch are derived, rising-pitch and falling-pitch trends in the strings of blocks, the secondary speech parameters are compared with predefined, subject independent values representing non-emotional speech to generate a processing result indicative of emotional arousal, and the generated processed result is outputted to an output device.
