历史上,宣化方言蟹止摄来母字韵母的读音呈地理分布南北各异、空间内部读音形式单一的格局,即北部读[-i],南部读[-eI]。如今,这种语音格局已经被打破,蟹止摄来母字韵母的读音在空间和年龄层上均发生了变异,其发展方向是向北京官话靠拢。 Historically, Xuanhua dialect crab only taken to the mother of the pronunciation of the mother was the geographical distribution of different north and south, a single internal spatial form of pronunciation pattern that read the northern [-i], read the southern [-eI]. Nowadays, the phonetic pattern has been broken, and the pronunciation of the mother-finacial constellation crab only mutates in both space and age. The direction of its development is to move closer to Beijing Mandarin.
