在各种实验和范例中，研究人员试图通过比较对语音音节的感知和对非语音类比的感知来确定言语知觉是否专门化。虽然非言语类比似乎是与言语的最佳比较，因为它们在声学上相似，但不被识别为言语相似，但有人认为，它们提供的比较令人困惑，无法解释。设计了两个实验来证明，在听觉感知中，当声音信号是机械事件的因果结果时，感知经验是机械事件本身的，而不是声音信号的。这有两个后果。一种是在语音和正弦波类比的比较中存在混淆，而被感知为语音的类比也有确定的因果来源，而另一种被感知为非语音的类比具有不确定或模棱两可的来源。第二，分类任务中的反应模式，如文献中用来比较语音和非语音的反应模式，将反映感知到的发声事件的属性；它们不会提供用于恢复事件属性的听觉系统过程的清晰窗口。实验3旨在表明，通过语音-正弦波比较的逻辑，对许多声信号产生事件的感知可能显得特别。即使是那些不能可信地被认为涉及专门化的事件。
In a variety of experiments and paradigms, researchers have attempted to determine whether or not speech perception is specializd by comparing perception of speech syllables to perception of nonspeech analogs. While nonspeech analogs appear optimal as comparisons to speech because they are acoustically similar without being recognized as speechlike, it is argued that the comparison they offer is confounded and uninterpretable. Two experiments are designed to show that, in auditory perception generally where acoustic signals are causal consequences of mechanical events, perceptual experiences are of the mechanical events themselves, not of the acoustic signal. This has two consequences. One is that there is a confounding in comparisons of speech with sine wave analogs that, whereas the one perceived as speech also has a definite causal source, the other, perceived as nonspeech, has an indeterminate or ambiguous source. A second is that response patterns in classification tasks such as those used in literature comparing speech to nonspeech will reflect properties of the perceived sound-producing event; they will not provide a clear window on auditory system processes used to recover event properties. Experiment 3 is designed to show that perception of many acoustic-signal producing events can appear to be special by the logic of speech-sine wave comparisons.sbd.even events that cannot plausibly be supposed to involve a specialization.
