长期以来，提高通信速率一直是 AAC 用户和设备制造商的目标。有证据表明，基于话语的方法有可能在不失去连贯性的情况下提供更快的速度。这里概述了体现这种方法的设备的历史发展。本说明重点介绍基于话语的设备 (UBD) 的理论起源以及这些设备产生的方法范围。接下来，讨论对话率和积极归因之间的因果关系问题。描述了最近支持因果关系的三项研究，随后描述了 UBD 与办公室环境中的构词系统之间的直接比较，其中涉及事务通信和社交聊天的混合。使用 UBD 时，对话率和感知的沟通能力都较高。最后，讨论了UBD未来发展的一些问题。
Increased communication rate has long been a goal of both individuals who use AAC and device manufacturers. There is evidence that utterance-based approaches have the potential to deliver faster rates without loss of coherence. An overview of the historical development of devices that embody such approaches is set out here. This account focuses on the theoretical origins of utterance-based devices (UBDs) and the range of approaches that these have produced. Next, the issue of a causal relationship between conversational rate and positive attributions is addressed. Three recent studies supporting a causal relationship are described, followed by an account of a direct comparison between a UBD and a word construction system in office environments that involved a mix of transactional communication and social chat. Conversational rate and perceived communicative competence were both higher when the UBD was used. Finally, some issues for the future development of UBDs are discussed.
