本文以有意义的双字组词语为语音材料,通过辨认实验和区分实验考察汉语普通话阳平调和上声调的听感分界。实验结果初步表明,阳上听觉感知属于范畴化感知。影响阳上听感分界的因素有很多,其中最主要的影响因素是目标字在双音节中处于前后字的不同位置,其次参照字的不同调类对阳上听感也有影响,此外实验呈现顺序等因素也对结果略有影响。 In this paper, we use the meaningful double-word phrase as the voice material to examine the sense of demarcation of the upper-tone tone of Chinese mandarin by recognizing experiments and distinguishing experiments. Preliminary results show that the auditory sense Yang belongs to the category of perception. There are many factors that affect the demarcation of the sense of yin yang, among which the main influencing factor is that the target word is located in different positions of the two syllables before and after the word, followed by different tones of the reference word also affect the sense of yang sense. In addition, Other factors also have a slight effect on the results.
