The purpose of this study was to find out whether deafened adults can take advantage of the extra information in speechreading given by the vibrational and motional patterns picked up by placing a hand on a speaker's throat and shoulder, and how valuable this tactile supplement is as a support system for speechreading. We have named this method--speechreading with tactile supplement--tactiling. Eight deafened adults participated in the study, conducted with a pre-test/post-test control group design. The experimental and the control groups took speechreading classes together. The experimental group received additional individual training in tactiling during six 1 h lessons. Both the experimental and the control groups were tested, before and after training, first by a familiar person and thereafter by an unfamiliar person. The results demonstrated two significant main effects. Tactiling is generally better than speechreading alone, and the results from the test given by the familiar speaker are better than with the unfamiliar speaker. The main effect of tactiling indicates that the method is worth pursuing as a communication system for the deafened adults. Possible reasons for the direct effect of tactiling are discussed, as well as modifications of this 'natural' device.
本研究的目的是探究成年聋人是否能够利用将手放在说话者的喉咙和肩膀上所获取的振动和运动模式，从唇读中获得额外信息，以及这种触觉补充作为唇读辅助系统的价值有多大。我们将这种方法——带有触觉补充的唇读——命名为触觉唇读。八名成年聋人参与了这项研究，采用前测/后测对照组设计。实验组和对照组一起参加唇读课程。实验组在六节1小时的课程中接受了额外的触觉唇读个人训练。实验组和对照组在训练前后，首先由熟悉的人进行测试，然后由不熟悉的人进行测试。结果显示出两个显著的主效应。触觉唇读总体上比单纯唇读效果更好，并且由熟悉的说话者进行测试的结果比不熟悉的说话者更好。触觉唇读的主效应表明，作为一种面向成年聋人的交流系统，该方法值得探索。文中讨论了触觉唇读直接产生效果的可能原因，以及对这种“自然”装置的改进。
