Tests of lipreading are valuable in many applications, particularly with hearing impaired people. Desirable properties of such a test are outlined, and the deficiencies of present tests noted. All the stated criteria are met by a new video recording of the BKB sentence lists. A calibration study with 22 normally-hearing subjects shows that 12 of the 21 lists may be considered equally difficult. Different scoring methods are investigated, including a subjective technique. Correlations among all the scoring methods are high. Practice effects can be large, and vary with lipreading ability. While low scorers show little increase in performance over the set of lists, high scorers show big improvements. Two examples of the test's usefulness are detailed--one from the laboratory and one from the clinic. Both demonstrate that hearing which would not lead to significant speech perception on its own can still greatly improve lipreading ability.
唇读测试在许多应用中都很有价值，尤其是对于听力受损者。本文概述了此类测试的理想特性，并指出了当前测试的不足之处。新录制的BKB句子列表视频满足了所有规定标准。一项针对22名听力正常受试者的校准研究表明，21个列表中的12个可被视为难度相当。研究了不同的评分方法，包括一种主观技术。所有评分方法之间的相关性都很高。练习效果可能很大，并且会因唇读能力而异。低分者在一组列表中的表现几乎没有提高，而高分者则有很大进步。详细介绍了该测试实用性的两个例子——一个来自实验室，一个来自诊所。两者都表明，单独听时无法带来显著言语感知的听力仍然可以极大地提高唇读能力。
