部分语音、部分形态条件的交替是语音理论的核心问题。在最优性理论中，提出了两种类型的解决方案：形态上专门的音系约束（界面约束）和针对不同形态类别（共音学）的不同约束排名。本文提供了区分这两种假设的经验证据。芬兰语中的词干元音交替受到一系列混合条件的控制，这些条件范围从纯粹的语音到形态和词汇，从铁定的例外规则到数量趋势。使用标准词典作为数据库，我们表明语音条件作用起着主导作用，但在语音条件不能确定输出的情况下，形态条件作用可能会出现。然后我们表明，常用于对变异进行建模的约束的偏序也可以扩展到形态条件。偏序模型是同音模型的限制版本，因此得到支持。
Alternations that are partly phonologically, partlymorphologically conditioned are a central problem in phonologicaltheory. In Optimality Theory, two types of solutions have beenproposed: morphologically specialized phonological constraints(interface constraints) and different constraint rankings fordifferent morphological categories (cophonologies). This paperpresents empirical evidence that distinguishes between these twohypotheses. Stem-final vowel alternations in Finnish are governed by amixed set of conditions that range from purely phonological tomorphological and lexical, from iron-clad exceptionless regularitiesto quantitative tendencies. Using a standard dictionary as the database, we show that phonological conditioning plays the dominant role,but in cases where phonology underdetermines the output, morphologicalconditioning may emerge. We then show that partial ordering ofconstraints, commonly used to model variation, extends tomorphological conditioning as well. The partial ordering model is arestrictive version of the cophonology model, which is thus supported.
