报告了两个关于自由回忆二分法呈现的合成语音的实验。第一个结果表明，右耳对于初始摩擦辅音的优势不仅是识别响应类别的函数，而且也是用于实现该响应的特定声音提示的函数。对于整个响应和组成的语音特征都是如此。第二个实验表明，当某些试验中出现的反应类别和特定刺激保持不变时，恒定刺激的右耳优势可能会受到实验中发生的其他刺激范围的影响。在实验中，当声道大小存在不确定性时，元音显示出右耳优势，但当实验中的所有元音都来自同一声道时，元音则不显示耳朵优势。这些结果被解释为表明，在信号的声学分析和将其识别为语音类别之间的某个阶段，耳朵之间，可能还有半球之间存在差异。
Two experiments on the free recall of dichotically presented synthetic speech sounds are reported. The first shows that the right ear advantage for initial fricative consonants is not simply a function of the recognition response class, but that it is also a function of the particular acoustic cues used to achieve that response. This is true both for the whole response, and for the constituent phonetic features. The second experiment shows that when both the response class and the particular stimuli presented on certain trials are held constant, the right ear advantage for the constant stimuli can be influenced by the range of other stimuli occurring in the experiment. Vowels show a right ear advantage when, within the experiment, there is uncertainty as to vocal tract size, but they show no ear advantage when all the vowels in the experiment are from the same vocal tract. These results are interpreted as demonstrating that there are differences between the ears, and probably between the hemispheres, at some stage between the acoustic analysis of the signal and its identification as a phonetic category.
