聲學(xué)線索掩蔽下普通話情感語音的聽辨研究

張高媛 王韞佳 黃靖雯

摘要 本文旨在研究經(jīng)過不同聲學(xué)處理的普通話情感語音信號的感知。實(shí)驗(yàn)中的感知刺激是攜帶中性、高興、恐懼、憤怒、悲傷、驚訝六種情感的語音，對這六種攜帶不同情感的自然語音進(jìn)行了低通濾波及平均時長與平均音強(qiáng)的歸一化處理。要求被試對自然語音刺激、濾波后語音刺激、濾波且歸一化后語音刺激進(jìn)行情感類型的辨認(rèn)。在部分語音線索掩蔽的情況下，聽者對于情感類型的識別正確率依然高于隨機(jī)水平。實(shí)驗(yàn)結(jié)果表明，情感聽辨的優(yōu)劣性差異較大；不同情感感知依靠的感知線索有可能不同；在不同語音條件下，情感之間的混淆模式雖不盡相同，但也有一定的相似之處。

The Perception of Emotional Speech under Acoustic Cues Masking in Mandarin

ZHANG Gaoyuan WANG Yunjia HUANG Jingwen

Abstract This paper aims to investigate the perception of emotional speeches that have gone through different acoustic masking processes in Mandarin. The perceptual stimuli in the experiment were speech items with 6 different emotions，i.e.，neutral，happy，scared，angry，sad and surprised. These natural speech items were low-pass filtered，and then normalized in duration and intensity. The experimental task was to identify the emotion type for all the natural and acoustically processed speech. The identification accuracies of emotional types were above chance level even when partial acoustic information was removed in the stimuli. The results demonstrated that（1）in Mandarin，the identification accuracies of each emotion were different；（2）different emotional speech perception might depend on different cues；（3）under the three stimulus conditions，the confusion patterns for emotions were also showed up differently，while there were still commonalities.
