People with aphasia may experience difficulties that prevent them from demonstrating in writing what they know and can produce orally. Voice recognition systems that allow the user to speak into a microphone and see their words appear on a computer screen have the potential to assist written communication.
This study investigated whether a man with fluent aphasia could learn to use Dragon NaturallySpeaking to write.
METHODS & PROCEDURES: A single case study of a man with acquired writing difficulties is reported. A detailed account is provided of the stages involved in teaching him to use the software. The therapy tasks carried out to develop his functional use of the system are then described. Outcomes included the percentage of words accurately recognized by the system over time, the quantitative and qualitative changes in written texts produced with and without the use of the speech-recognition system, and the functional benefits the man described.
OUTCOMES & RESULTS: The treatment programme was successful and resulted in a marked improvement in the subject's written work. It also had effects in the functional life domain as the subject could use writing for communication purposes.
The results suggest that the technology might benefit others with acquired writing difficulties.
失语症患者可能会遇到一些困难，这些困难使他们无法通过书写来展示自己所知道的以及能够口头表达的内容。语音识别系统允许用户对着麦克风说话，并在电脑屏幕上看到自己说出的文字，这有可能辅助书面交流。
本研究调查了一名患有流利性失语症的男性是否能够学会使用“自然语音”软件进行书写。
报告了一名患有后天性书写困难男性的单病例研究。详细介绍了教他使用该软件所涉及的各个阶段。接着描述了为促进他对该系统的功能性使用而开展的治疗任务。结果包括随着时间推移系统准确识别的单词百分比、使用和不使用语音识别系统时所产生书面文本的数量和质量变化，以及该男性所描述的功能益处。
治疗方案取得成功，该受试者的书面作业有显著改善。在功能生活领域也产生了效果，因为该受试者能够将书写用于交流目的。
结果表明，这项技术可能会使其他患有后天性书写困难的人受益。
