广州话平调的感知
Perception of Cantonese tones

为研究平调感知机制，该文以广州话自然语言中的单字和双字词为实验语料，采用“对角/半空间测试法”，通过辨认实验和区分实验考察了广州话高中低3个平调的听感范畴。结果表明：广州话单字组高平调和低平调均存在各自听感空间，中平调的听感空间与低平调大幅重叠，呈现出与低平调混淆的迹象，这与其声学空间表现一致。双字组的辨认边界与区分峰值呈现出明显的峰界对应，具有明显的范畴边界。参照字的不同声调和目标字的前后位置都会影响范畴边界位置。
Abstract：The perceptual of Cantonese speeds tones was investigated for the perceptual of three tones on identification and discrimination experiments. This research used a Cantonese natural language monosyllabic and disyllabic corpus as the speech material with identification and discrimination experiments based on the "Diagonal/Half Space Test Method". The monosyllable tests showed that the three groups of high and low tones have their own perceptual space with the perceptual space of the low tones substantially overlap pins that of the mid level tones, which is consistent with the acoustic space of these tones. The bisyllable tests indicate that the perceptual category is certain with a clear categorical boundary. The different tones of the reference words and the first part or the last part of disyllabic words affect the categorical boundary location.
