针对语言发音特点中鼻音的前后位置问题,通过对同心方言与普通话的比较,发现同心方言不但有将前鼻音读为后鼻音的情况,同时还有将后鼻音读为前鼻音的情况。文章认为这一特殊的发音特点与回族先民的母语阿拉伯语、波斯语有着紧密的联系。也就是说,以同心方言为代表的回族的鼻音特点是受其先民母语阿拉伯语、波斯语的影响而形成的。 According to the comparison of concentric dialects and mandarin, we find that the concentric dialects not only have the former nasal sounds read as nasal nasal sounds, but also the nasal nasal sounds as the former nasal sounds. The article holds that this particular pronunciation feature is closely related to the Arabic and Persian language of the Hui people’s ancestors. In other words, the nasal features of Hui people, represented by concentric dialects, are influenced by the Arabic and Persian language of their ancestors’ mother tongue.
