In two experiments, the perception of words in sentences was measured by speechreading with and without tactile presentation of voice fundamental frequency (F0). The first experiment involved normally hearing subjects and two kinds of tactile display of F0: (1) a spatial, multichannel display; and (2) a temporal, single-channel display. Mean performance with the tactile displays was found to be slightly, but significantly, better than speechreading alone, but no significant difference was found between the two displays. The second experiment involved hearing-impaired subjects and only the spatial, multi-channel display of F0. For all three subjects, after extended training, speechreading performance was significantly better with the addition of the tactile display than by speechreading alone. The improvement amounted to reductions of word recognition error of 24, 33, and 50% in the three subjects.
在两项实验中，通过在有和没有语音基频（F0）触觉呈现的情况下进行唇读来测量句子中单词的感知。第一个实验涉及听力正常的受试者以及两种F0触觉显示方式：（1）空间多通道显示；（2）时间单通道显示。结果发现，使用触觉显示时的平均表现略好于仅唇读，但有显著差异，不过两种显示方式之间未发现显著差异。第二个实验涉及听力受损的受试者，且仅采用F0的空间多通道显示。对于所有三名受试者，经过长期训练后，添加触觉显示后的唇读表现明显优于仅唇读。三名受试者的单词识别错误率分别降低了24%、33%和50%。
