觀音橋話(中國四川省金川縣觀音橋鎮轄區及其鄰近一帶語言)以往學者們看作嘉戎語或道孚語的方言。本文通過約1700條包含基本詞在內的常用詞和幾項獨特語法現象的比較，認為觀音橋話應是獨立於嘉戎語和道孚語之外的語言，並根據其核心地帶居民自稱將這種語言命名為拉塢戎語。通過比較，更加看清了拉塢戎語、道孚語、嘉戎語包括尚未進行比較研究的卻域語是一組在發生學的關係上非常密切的語言，在羌語支之下建立嘉戎語分枝的意見值得重視。

Guanyinqiao speech (spoken in Guanyinquiao Town and its neighboring areas in Jinchuan County, Sichuan Province of China) used to be viewed by scholars as dialect rGyalrong or Daofu Languages. By comparison of about 1,700 everyday expressions, including basic words, and a few peculiar grammatical phenomena, the author of the article demonstrats that Guanyinqiao speech should be considered to be a separate language, and not a dialect of rGyalrong and Daofu languages. The author also names this speech as Lavrung language according to the way of calling its core zone by itself.
