Abstract：Dearing is a special kind of emotional speech. For emotion classification, dearing is not a mood or attitude, but a mode of speech which demonstrates a strong emotional activity. This study analysizes the dearing characteristics in terms of the fundamental frequency (f0) with the most obvious characteristic of "dearing" being the raised f0, which is not a constant increment, but is related to the tones, genders and vowels, with changes in the shapes of the f0 graphs and the tone register. This study also examines how the f0 transformation is related to dearing with sample syntheses and perceptional recognition, and demonstrates that the pitch increment typically shows the activity of dearing in the arousal dimension of emotional speech. The increment of f0 is crucial to dearing yet it is not the only feature nor the sufficient condition of recognition.
