中文摘要：

本文通过两个听辨实验，采用强迫分类和相似度评分的方法，探讨了普通话母语者对粤语声调的感知规律。实验表明，普通话母语者对声调的感知匹配首要依据是声调的调型，而调阶和时长都起着重要的作用。声调的调阶会影响到相似度评分。粤语的三个平调／55/、／33/、/22／与普通话第一声匹配程度较高；粤语阴上/35/、阳上／13/两个升调，与普通话第二声相匹配，且相似度评分无显著差异。粤语的阳平／21/和阳上/13/因调型与普通话第三声有类似之处，因此形成一定程度的匹配关系。普通话母语者对粤语入声的感知比较复杂，上阴人和阳人大部分归为普通话第一声，其余归为第四声。下阴入两次实验结果不一致，具体原因还需进一步研究。

英文摘要：

This paper is intended to investigate how native Mandarin speakers perceive Cantonese tones. Two auditory experiments have been conducted. In experiment I, Mandarin speakers had to classify the tones of Cantonese stimulus words into Mandarin tone categories and evaluate the similarities between them. In experiment Ⅱ, Mandarin speakers had to identify which one of the two Mandarin candidates similar to the Cantonese stimulus. It is showed that the three level tones of Cantonese, yinping/55/, yinqu/33/, and yangqu /22/ were mapped onto Mandarin/55/. The two rising tones of Cantonese, yinshang/35/, and yangshang/13/, were mapped onto Mandarin/35/. The low-falling tone, yangping/21/, and the light rising tone, yangshang /13/ of Cantonese were mapped onto Mandarin/214/to a certain extent. In conclusion, the pattern of pitch has played an important role in the perception of tone by native Mandarin speakers. The register and duration also have impact on the tone perception.
