the correlation between intonational contours and emotion in persian speech, using rise/fall connection model

the present study provides an analysis of the correlation between acoustic properties, duration and pitch amplitude of speech associated with three basic emotions: anger, sadness and joy against neutrality as a reference, emotionally expressed by six persian speakers. rise/fall connection model (taylor, 1995) is used to analyze acoustic parameters and measure how an utterance is modulated when persian speaker's emotion deviates from neutral to certain emotional states. praat (boersmal and weenink, 2006) speech processing software is used to calculate the pitch contour of each utterance. statistical analysis is also used to indicate that strict acoustic correlation exists between sadness and neutrality on the one hand and between anger and joy on the other.
