One hundred and eighty speech and language therapists throughout the UK completed a postal questionnaire which asked for ratings of visual speech aids (VSAs) on a number of dimensions together with information regarding frequency of use of such aids, comments on the range of applicability of each type of aid and other demographic data relating to the diversity of client groups covered in case loads. The results (using analysis of variance) revealed a main effect of VSA type. There was also a main effect of question type; all VSAs scored poorly on some dimensions as compared with others. Furthermore there was a significant interaction between type of VSA and dimension type. This suggests that VSAs not only tend to be built for particular client groups, but that the makers tend to focus on some specific design criteria to the detriment of others. These results are discussed with respect to the future design of VSAs, and with respect to their testing and future evaluation.
全英国的180名言语治疗师填写了一份邮寄问卷，问卷要求他们对视觉言语辅助工具（VSA）在多个维度上进行评分，同时提供有关此类辅助工具使用频率的信息、对每种辅助工具适用范围的评论，以及与病例负荷所涵盖的客户群体多样性相关的其他人口统计学数据。结果（使用方差分析）显示VSA类型存在主效应。问题类型也存在主效应；与其他维度相比，所有VSA在某些维度上得分较低。此外，VSA类型和维度类型之间存在显著交互作用。这表明VSA不仅倾向于为特定客户群体设计，而且制造商往往侧重于某些特定设计标准而损害了其他标准。将针对VSA的未来设计、测试和未来评估对这些结果进行讨论。
