发嗲是一种特殊的情感语音。该文从情感类型的角度出发,认为发嗲并非简单的某种情绪或态度,而是一种情感上主动性强的言语模式。该文提取了发嗲在基频上的特征,发现其在基频上最显著的特征是基频提高,这种提高并非整体的同步提升,而是与调类、性别、元音等因素有关,并且伴随着基频曲线形状和基频范围的变化。该文通过语音合成和听辨实验来检验基频变化对发嗲的意义,实验表明基频的提高突出体现了发嗲在情感激发维上的主动性特征。基频提高是发嗲的关键因素,但不是唯一特征,也不是听辨的充分条件。
"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, hut 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.
