People with aphasia often have reading impairments that affect participation in daily activities. Text-to-speech (TTS) devices are technology-based supports that can facilitate processing of written materials. The purpose of this study was to gather information about the reading behaviors and TTS technology perceptions of people with aphasia who had first learned about system features and options. Sixteen people with chronic aphasia participated in single, one-on-one instructional and guided practice sessions using TTS systems. They answered close-ended questions about current reading behaviors and materials and ways they believed these would change given TTS system access. Participants reported reading at home and community locations. Most read calendars, newspapers, magazines, and mail. Participants who did not read lengthy materials - such as newspapers, magazines, and novels - indicated their interest in these materials would likely increase given TTS support. Although participants did not predict substantial comprehension changes given TTS support, most expressed interest in the technology after learning about it. Thus, people with aphasia perceive TTS systems as helpful for comprehending lengthy materials. Given modest predictions about comprehension benefits, presenting TTS as one of several support strategies is an appropriate recommendation.
患有失语症的人常常存在阅读障碍，这会影响他们参与日常活动的能力。语音合成（TTS）设备是一种基于技术的支持，可以帮助处理书面材料。本研究的目的是收集有关首次了解系统功能和选项的失语症患者的阅读行为和 TTS 技术感知的信息。16 名慢性失语症患者参加了使用 TTS 系统的一对一指导和实践课程。他们回答了关于当前阅读行为和材料以及在获得 TTS 系统支持后他们认为这些行为和材料会如何改变的封闭式问题。参与者报告在家中和社区地点阅读。大多数人阅读日历、报纸、杂志和邮件。不阅读长篇材料（如报纸、杂志和小说）的参与者表示，他们对这些材料的兴趣可能会因 TTS 支持而增加。尽管参与者没有预测到 TTS 支持会带来实质性的理解变化，但大多数人在了解 TTS 后表示对该技术感兴趣。因此，失语症患者认为 TTS 系统有助于理解长篇材料。鉴于对理解益处的适度预测，将 TTS 作为几种支持策略之一推荐是合理的。
