汉语自然话语的音高下倾

Pitch Declinatoin of Chinese Spontaneous Speech

该研究使用电话对话语料,在统计的基础上对语句的音高下倾进行了考察。发现绝大多数语句的音高都是逐渐下降的,音高曲线前高后低的走势有其生理上的原因,并且具有标界功能。少数语句音高不下降,这与词语的载义重度、焦点及音节本调有关。该文又对陈述句和疑问句的音高进行了考察,发现与陈述句相比,疑问句的整体音域较大,句末无疑问语气词的是非问句末尾两音节间的降幅较小。

In this paper, based on a telephone conversation corpus, the pitch declination of sentence is done. It is found that pitch declination occurs in most cases, which is due to physiological reason, and there is demarcative function as well. In some cases declination does not occur, and this is related to semantic strength, focus and tone. The pitch representation of statement and question is analyzed, and it is found that compared to statement, the pitch range is great for question. The pitch drop is the least between the final two syllables for yes-no question without final particle.
