宜宾方言单字调声学实验研究

摘要

The method of experimental phonetics is adopted to analyze the monosyllabic tone of the Yibin dialect. According to the acoustic experimental data, the tone-marks of degrees are defined as follows:there are five tone classes in Yibin dialect, the first tone is Yinping, the second Yangping, the third Shangsheng, the fourth Qush-eng, and the fifth Rusheng;and the pitch of Yinping is 35, Yangping 31, Shangsheng 51,Qusheng 212, Rush-eng23. The comparison of the length of duration are showed in descending order as follow:Qusheng>Rusheng>Yinping>Shangsheng>Yangping. YinBin dialect has displayed an evolvement of vanishing of tail vowel in ente-ring tone, which is not necessarily longer than relaxation tones.%采用实验语音学的方法研究当代宜宾方言单字音声调的音高以及调长特征。根据实验结果,宜宾方言共有阴平、阳平、上声、去声和入声五个调类,音高调值为：阴平35、阳平31、上声51、去声212、入声23,时长的长短关系为：去声>入声>阴平>上声>阳平。宜宾方言的入声处在发生“入声舒化”的演变中,促声调时长不一定比舒声调时长短。
