Abstract 摘要
This is a review of the book on a dialogue on sound change between William Labov and William S-Y. Wang at the Chinese University of Hong Kong in May 2012. First Labov’s and Wang’s Presentations are surveyed. Then the regular sound changes Labov discusses are examined, and Neogrammarian regularity and lexical diffusion in sound change are synthesized. The 2-dimensional lexical diffusion model, depending on the relative ratios of W(ord)-diffusion and S(peaker)-diffusion, synthesizes lexical diffusion and Neogrammarian regularity. It assumes that in Neogrammarian regularity W-diffusion proceeds so fast that it is difficult to observe it within each individual, but the change can be observed while it is in progress across generations. The empirical evidence of the rapid W-diffusion is also given.

本文书评《拉波夫与王士元对话: 语音变化的前沿问题》。作者首先查解了拉波夫与王士元的讲演。然后对拉波夫关于规则语音变化的讨论作了查析，同时将语音变化里新语法学派的规则性及词汇扩散论作整和讨论。词-扩散及说话者-扩散相对比率的二维词汇扩散模式使词汇扩散与新语法学派的规则性得以整和。看起来，依新语法学派规则性的词-扩散快的难以根据每个说话者的情况观察到，但它却可以在跨世代进程中观察到。速率词-扩散的经验证据可供参考。
