本文以求吉乡麻藏村口语为例,扼要介绍求吉藏语音系及其源流。麻藏话现代音系的突出特点:音节构造简单,发声类型有辨义作用,无音位调。历史音变的突出特点:古不带前置非鼻辅音之全清、全浊声母均读全浊,而带前置非鼻辅音之全浊声母清化后读气嗓音等。求吉藏语在藏语方言中之地位尚待确定。 This article takes Ma Zangcun colloquial in Jixiang as an example, and briefly introduces the phonological system of Jizang Tibetan and its origins. Tibetan Tibetan modern salient features: Syllabic structure is simple, the sound type has the role of differentiation, no tone adjustment. The salient features of historical tone: the ancient non-nasal consonant with the whole ancient clear, voiced consonants are read all voiced, and with non-nasal consonants pre-voiced consonants after the voicing of clear air to read the voice and so on. The status of seeking the Kyrgyz language in Tibetan dialects has yet to be confirmed.
