本文利用实验语音学的方法考察辉县方言的声调演化规律,总结其单字音声调格局。结果发现:辉县方言仍保留了平上去入四大声调类型,其中平分阴阳、清上和次浊上仍归上、全浊上归去、去声和入声不变调。不过去声调较之前变化显著,究其原因,猜想源于普通话的推广对方言的影响。 In this paper, we use the method of experimental phonetics to investigate the tone evolution of Huixian dialect, and summarize the tone structure of its pronunciation. The results showed that: Huixian dialect still retained flat into the four major types of tone, of which the yin and yang, Qing and sub-turbidity is still on the return of all turbidity on the go, the sound and tone unchanged. However, the past tone was significantly different from before. The reason for this is that the conjecture stems from the promotion of Putonghua on the dialect.
