In modern Chinese, the [vi sound—derived from Middle Chinese [v]+[i]— persists in Central Plains Mandarin and beyond, exhibiting diachronically stratified pronunciation across five regional categories in China and abroad, shaped by historical geography, warfare, and commerce. Focusing on six Zhi-category characters (味,唯,微,惟,未,维) with Yu-Wei initials and rounded vowels, this study takes Central Plains Mandarin as its primary field, drawing on the Guangyun and Zhongyuan Yinyun to trace their spatio-temporal evolution. Grounded in Dai Zhen's phonetic transformation theory, it reveals the bidirectional closed-loop mechanism of "initials driving rhyme differentiation and finals reinforcing initial assimilation," extending traditional explanatory scope. Comparing three domestic dialect types (Central Plains Mandarin, Wu, southern peripheral dialects) with two overseas materials (Central Asian Dungan Mandarin islands and Sino-Vietnamese phonology), it demonstrates that [vi] constitutes stratified remnants of different diachronic stages, with overseas materials complementing domestic dialects. This study provides empirical evidence for interdisciplinary research bridging historical phonology and dialect geography, with both academic and cultural value.

现代汉语中零声母[w]+韵母[ei]的字在演变过程中依然在中原官话等地区存在中古 [v]声母+[i]韵母的[vi]音字。而中原官话作为[vi]音的发展禀赋，在历史地理、战争、 商贸交流等因素的作用下，在境内外五类地区中依然有历时分层语音留存现象。因此本文 以现代方言中喻微母止摄合口“味、唯、微、惟、未、维”六字为核心研究对象，以中原 官话为核心考察区域，结合广韵、中原音韵等历史文献系统梳理该类字音的时空演变 脉络。研究以戴震转语理论为核心线索，一方面揭示“声母驱动韵分、韵母强化声合”的 声韵双向闭环机制，拓展了传统转语理论的解释边界;另一方面结合地理阻隔、社会整合 等历史地理因素，通过中原官话、吴语、南方边缘方言三类境内材料，与中亚东干语、越 南汉越音及韩日两国发音三类域外材料的对比互证，而境内外[vi]音分属不同历时阶段的 分层留存，域外材料可与境内方言形成互补印证。本研究为历史音韵与方言地理学的交叉 研究提供了材料实证，兼具学术与文化价值。
