On the basis of a number of vowel and stop-consonant discrimination experiments (AX and 2IFC fixed and roving) with natural stimuli, it is concluded that stop-consonant perception is highly categorical: there were few significant differences between the discrimination results and the phoneme identification results. Moreover, the discrimination and identification response maxima differed significantly from the other data points. Vowel perception was much less categorical: the maxima in the functions were much less significant, and there were significant differences between the various paradigms. Consonant discrimination was much less (if at all) subject to range effects than vowel discrimination. All these results point to different memory types for stop consonants and vowels, and, consequently, to a combination of two different theories of speech sound discrimination: dual-process theory (DPT) for consonants, and trace-context theory (TCT) for vowels.
基于一系列使用自然刺激进行的元音和塞音辨别实验（AX以及固定和移动的2IFC），得出的结论是，塞音感知具有高度的范畴性：辨别结果与音素识别结果之间几乎没有显著差异。此外，辨别和识别反应的最大值与其他数据点有显著差异。元音感知的范畴性要小得多：函数中的最大值不太显著，并且不同范式之间存在显著差异。与元音辨别相比，辅音辨别（如果有的话）受范围效应的影响要小得多。所有这些结果都指向塞音和元音的不同记忆类型，因此也指向了两种不同的语音辨别理论的结合：辅音的双过程理论（DPT）和元音的痕迹-语境理论（TCT）。
