本文通过发音实验对两组美国生(语言学习时间分别为:三个月和一年)的双音节汉语声调进行了调查。实验结果表明:(1)一年组学生的声调发音准确率比三个月组的学生高;(2)一年组学生声调发音的准确率受声调环境和声调位置的影响比三个月组的学生小;(3)声调环境对阴平的准确率有影响,阴平在同调连发顺序和相容声调环境下的准确率比在异调连发顺序和相斥声调环境下高;(4)声调位置对阳平和去声的准确率有影响,阳平的准确率在末音节位置比在首音节位置高,去声情况与阳平相反。
In this paper, two-syllable Chinese tonalities of two American students (language learning time: three months and one year respectively) were investigated through pronunciation experiments. The experimental results show that: (1) the accuracy rate of tone pronunciation of students in one-year group is higher than that of students in three-month group; (2) The accuracy of pronunciation of students in one-year group is influenced by tone environment and tone position more than those in three-month group (3) The tonal environment has an impact on the accuracy of Yin Ping, and the accuracy rate of Yin Ping under the homophonic sequential order and the compatible tonal environment is higher than that in the tonal sequence and the repulsive tonal environment. (4) The location of the tone has an impact on the accuracy of the yangping and the sounding. The accuracy of the yangping is higher at the last syllable than at the syllable, and the sounding situation is opposite to that of the yingping.
