本文基于石锋(1999)语调格局及语调层级的理念,采用起伏度的计算与对比的研究方法,对四位香港粤语发音人的无疑问词的疑问句语料进行起伏度的量化分析,考察疑问句句调域、词调域、字音调域的音高表现,并与陈述句的语调进行对比。研究发现:舒声调疑问句整体调域的提高和扩展,主要表现在句末词调域末字调域的大幅度加宽和扩展,成为疑问句语调音高表现的重要特征。人声调疑问句句末词调群末字调域的加宽幅度小于舒声调,承载边界调的能力变弱。疑问句音高的最高点在句末词调域的上线,陈述句在句首词调域的上线,音高的最低点,舒声调的疑问句和陈述句均在句末词调域的下线,入声调在句末词调域中字的下线。 Based on Shi Feng (1999) intonation pattern and the concept of intonation level, this paper uses the method of calculating and contrasting the ups and downs to quantify and analyze the questionable corpus of four Cantonese speakers who have no question in Hong Kong. Tune domain, Tone domain, Pitch domain pitch performance, and with the sentence intonation contrast. It is found that the improvement and expansion of the overall tone domain of the Shusheng question question mainly manifests itself in the substantial widening and expansion of the domain words at the end of the sentence, which becomes an important feature of the tone pitch performance of the question sentence. Person’s tone question sentence at the end of the phrase group tune the scope of the end of the tune is less than the tune of tone, bordering the ability to adjust the boundaries become weaker. The highest point of the interrogative sentence pitch is at the end of the last line of the sentence, the last line of the sentence at the beginning of the sentence, the lowest point of the pitch, the interrogative sentences and the statement sentences of the comfortable tone are off the assembly line at the end of the sentence, Word in the field of words offline.
