ABSTRACT

In this paper, we examine the role of emotional acoustic cues including both prosody and voice qualityparameters for the modification of a word sense. For the extraction of prosody parameters and voicequality parameters, we used 60 pieces of speech data spoken by six speakers with five different emotionalstates. We analyzed eight different emotional acoustic cues, and used a discriminant analysis technique inorder to find the dominant sequence of acoustic cues. As a result, we found that anger has a close relationwith intensity level and 2nd formant bandwidth range; joy has a relative relation with the position of 2nd and 3rd formant values and intensity level; sadness has a strong relation only with prosody cues such asintensity level and pitch level; and fear has a relation with pitch level and 2nd formant value with itsbandwidth range. These findings can be used as the guideline for find-tuning an emotional spokenlanguage generation system, because these distinct sequences of acoustic cues reveal the subtlecharacteristics of each emotional state.
