1目前关于触觉辅助设备对听障者言语感知的有效性的研究表明，持续数月或数年的大量培训对使用者从触觉设备中获得最大益处是必要的。许多研究已经证明了包括分析成分（如音素训练）以及更多合成任务（如句子识别和语音跟踪）的训练计划的有用性。然而，特别是在儿童项目中，最好是组织培训经验，以便首先培训容易的区别，然后再培训更难的区别。在本研究中，系统的评价音素水平的信息提供的Tactaid VII，多通道触觉援助，进行。成年受试者进行了测试，在最小的对和封闭设置的音素歧视和识别任务下的触觉援助，speechreading单独，speechreading加上触觉援助条件下，提供一个清单的刺激可识别性和许可证的歧视容易或更困难的排名。由于这些排名可能会有所不同的协同发音效果的功能，三个不同的元音背景下进行了测试的辅音刺激。结果表明，确实有相当大的差异，元音上下文中，Id元音上下文产生了最可识别的刺激。这些数据可以被教师和治疗师用来构建可行的刺激集，用于触觉辅助用户的培训计划。
1 Current research on the effectiveness of tactile aids for speech perception by hearing-impaired persons suggests that substantial training, lasting over months or years, is necessary for users to achieve maximal benefits from a tactile device. A number of studies have demonstrated the usefulness of training programs that include an analytic component, such as phoneme training, together with more synthetic tasks such as sentence identification and speech tracking. However, particularly in programs for children, it is desirable to structure training experiences so that easy distinctions are trained first, and more difficult distinctions are approached only later in training. In the present study, a systematic evaluation of phoneme-level information provided by the Tactaid VII, a multichannel tactile aid, was performed. Adult subjects were tested in minimal pairs and closed set phoneme discrimination and identification tasks under tactile aid alone, speechreading alone, and speechreading plus tactile aid conditions, to provide an inventory of stimulus identifiability and permit ranking of discriminations as easy or more difficult. Because these rankings might differ as a function of coarticulation effects, three different vowel contexts were tested for consonant stimuli. Results indicated that there were indeed considerable differences across vowel contexts, and that the Id vowel context yielded the most identifiable stimuli. These data could be used by teachers and therapists to construct viable stimulus sets for training programs for tactile aid users.
