【摘要】 本文对从自然语料中获取的,包含去声和轻声音节的双音节韵律词的音高、音长进行了系统的研究。研究结果表明,边界类型对处于双音节词前音节位置的去声音节影响不明显,对处于后音节位置的去声音节的影响则较为显著;句中短停顿前的去声音节的时长最长;语流中阳平的高音特征和去声的低音特征容易被弱化。对同为“降”调型的去声和轻声的考察结果表明,语流中的去声与轻声存在一定程度的趋同倾向,阳平后的轻声容易发生“去声化”,去声后的去声容易发生“轻声化”。更多还原

【Abstract】 The pitch and duration of disyllabic words which contain Mandarin tone-4 and tone-5 had been systemically studied on the basis of natural utterances.The result showed:1)when tone-4 was located in the former syllable,the effect of the break level was not distinct,whereas in the later syllable,the effect was distinct.2)in front of the shorter break,the duration of tone-4 was the lon- gest.3)the low feature of tone-4 and the high feature of tone-2 were often induced in natural utter- ances.4)comparisionof tone-4 with tone-5 showed that tone-4 and tone-5 were often neutralized, tone-5 in back of tone-2 was similar to tone-4,and tone-4 in back of tone-4 was similar to tone-5.更多还原
