在这里报告的实验中，听者分类和区分语音和非语音模拟刺激，其中元音和后面的辅音或它们的类似物的持续时间是正交变化的。听者的母语在这些持续时间在说话者产生这些序列时的协同变化方面存在差异。因为言语感知的听者模型和自主模型假设，两种刺激所唤起的听觉品质决定了他们最初的感知评估，他们都预测，在两种任务中，来自所有语言的听众对非言语类似物的反应与他们对言语的反应相似。因为直接现实主义模型和互动模型都没有假设这样一个加工阶段，他们预测听者母语中元音和辅音持续时间的协同变化将决定他们如何对言语刺激进行分类和区分，并且所有听者对非言语刺激和言语刺激的分类和区分都会有所不同。听者对言语刺激的分类确实因其母语中这些持续时间的变化而有所不同，但所有听者对言语刺激的区分方式都是相同的，对非言语刺激的分类和区分方式也都是相同的。这些相似性可能来自于听者在这些刺激的任务中添加元音和辅音间隔（或其类似物）的持续时间；当语言经验不影响他们感知这些持续时间时，他们就会这样做。这些结果支持一种自主而非互动的模式，即听者在后感知处理阶段添加或应用他们的语言经验。然而，他们并不支持听力学模型而不是直接现实主义模型，因为他们没有提供证据表明信号的声学特性在假设的先验感知阶段发生了变化。
In the experiments reported here, listeners categorized and discriminated speech and non-speech analogue stimuli in which the durations of a vowel and a following consonant or their analogues were varied orthogonally. The listeners’ native languages differed in how these durations covary in speakers’ productions of such sequences. Because auditorist and autonomous models of speech perception hypothesize that the auditory qualities evoked by both kinds of stimuli determine their initial perceptual evaluation, they both predict that listeners from all the languages will respond similarly to non-speech analogues as they do to speech in both tasks. Because neither direct realist nor interactive models hypothesize such a processing stage, they predict instead that in the way in which vowel and consonant duration covary in the listeners’ native languages will determine how they categorize and discriminate the speech stimuli, and that all listeners will categorize and discriminate the non-speech differently from the speech stimuli. Listeners’ categorization of the speech stimuli did differ as a function of how these durations covary in their native languages, but all listeners discriminated the speech stimuli in the same way, and they all categorized and discriminated the non-speech stimuli in the same way, too. These similarities could arise from listeners adding the durations of the vowel and consonant intervals (or their analogues) in these tasks with these stimuli; they do so when linguistic experience does not influence them to perceive these durations otherwise. These results support an autonomous rather than interactive model in which listeners either add or apply their linguistic experience at a post-perceptual stage of processing. They do not however support an auditorist over a direct realist model because they provide no evidence that the signal’s acoustic properties are transformed during the hypothesized prior perceptual stage.
