In studying language change, Ohala and Lorentz (1977) observed that when the labial-velar glide [w] occurs adjacent to fricative noise, the resulting complex of acoustic features is most often perceived and pronounced as a labial, rather than a velar consonant. However, contemporary Spanish, as spoken in Mexico and the U.S. Southwest, presents a somewhat different pattern. The current research examined two directional predictions based on Ohala and Lorentz (1977) with reference to the perception and production of Spanish fricatives by Chicano children and adults: A Differential Effect of Context hypothesis (more labial/velar fricative interchanges will occur before rounded, rather than unrounded vowels or glides), and a Labial Predominance hypothesis (before a following rounded vowel or glide, labial fricatives will be favored in labial/velar interchanges). Results of perceptual tests provided support for these acoustically-based predictions, but subjects' productions also showed strong influence from sociolinguistic factors in the opposite direction.
在研究语言变化时，奥哈拉和洛伦兹（1977年）观察到，当唇软腭滑音[w]出现在擦音噪音附近时，由此产生的复杂声学特征通常被感知和发音为唇音，而不是软腭辅音。然而，在墨西哥和美国西南部所讲的当代西班牙语呈现出一种略有不同的模式。当前的研究基于奥哈拉和洛伦兹（1977年）的研究，针对奇卡诺儿童和成年人对西班牙语擦音的感知和发音检验了两个方向性预测：语境差异效应假说（在圆唇元音或滑音之前，而不是非圆唇元音或滑音之前，会出现更多的唇音/软腭擦音互换）和唇音优势假说（在后续的圆唇元音或滑音之前，唇音擦音在唇音/软腭音互换中更受青睐）。感知测试的结果为这些基于声学的预测提供了支持，但受试者的发音也显示出社会语言因素在相反方向上的强烈影响。
