Tactiling is the name given to a method of tactually supplementing speechreading. According to this method a deaf speechreader places his hand on a talker's shoulder with his fingers lightly against the neck thus obtaining clues relating to consonant production. The method was invented by a postlingually deafened Swedish male, Gustaf Soderlund, and has been studied since 1986 by several investigators including one of the applicants for this grant (Plant). Mr. Soderlund's performance is outstanding and the method has been found to be effective on 24 postlingually deafened subjects even without training (Ohngren 1992). An experimental device called a "Tactilator" was built and tested by Ohngren and it was shown that by using a contact microphone on the neck, in place of direct hand contact, that similar information could be transmitted. During the Phase I study we were able to show that an air microphone with certain processing procedures could give results similar to the contact microphone, but that Mr. Soderlund still preferred the contact microphone. In this Phase II work we will investigate the processing methods further, both on Mr. Soderlund and on a larger population, and field evaluate the best of the tactilator processing methods with the view of designing a commercial unit. PROPOSED COMMERCIAL APPLICATION: The commercial production of this device is assured. It would be a low cost device for aiding the postlingually deaf in speechreading. The key issue is that its low cost and convenience would increase the market size in as much as all present devices are quite expensive and probably do not offer greater advantage for this population.

触觉是一种触觉补充方法的名称 语音阅读。根据这种方法，聋人的演讲者将他的 用手指轻轻靠在脖子上的说话者的肩膀上 从而获得与辅音生产有关的线索。该方法是 由后后聋哑的瑞典男性Gustaf Soderlund发明的， 自1986年以来，几位调查人员都对其中一名调查员进行了研究 该赠款的申请人（工厂）。 Soderlund先生的表现是 出色的，该方法已被发现有效24 即使没有培训，后聋的受试者也会聋（Ohngren 1992）。 由一个称为“战术机”的实验设备由 ohngren，显示出通过在脖子上使用触点麦克风， 代替直接接触，类似的信息可能是 传输。 在我研究的阶段中，我们能够证明空气 具有某些处理程序的麦克风可能会提供类似的结果 接触麦克风，但Soderlund先生仍然更喜欢 接触麦克风。 在这第二阶段的工作中，我们将调查 在Soderlund先生和更大的 人口，现场评估战术机构的最佳处理 设计商业单元的方法。 拟议的商业应用：该设备的商业生产 保证。这将是一个低成本的设备 聋哑人的语音阅读。关键问题是其低成本和便利性 与所有当前设备一样，会增加市场规模 非常昂贵，可能没有更大的优势 人口。
