听觉用户界面对于数十亿有视觉障碍、读写能力有限、正在开车或因其他原因无法使用视觉界面的人来说，在网络访问方面具有巨大潜力。然而，基于语音的顺序呈现方式只能传达有限的信息。此外，典型的听觉用户界面失去了诸如文本样式和页面结构等视觉线索，并且缺乏关于当前焦点的有效反馈。为了解决这些局限性，我们创建了“Sasayaki”（在日语中是“低语”的意思），它通过自动或响应用户请求，用与上下文相关信息的次要低语来增强主要语音输出。它还提供了跳转到语义上有意义位置的新方法。一个原型被实现为一个听觉网络浏览器的插件。我们的实验结果表明，Sasayaki可以减少在网页中查找元素的任务完成时间，并提高满意度和信心。
Auditory user interfaces have great Web-access potential for billions of people with visual impairments, with limited literacy, who are driving, or who are otherwise unable to use a visual interface. However a sequential speech-based representation can only convey a limited amount of information. In addition, typical auditory user interfaces lose the visual cues such as text styles and page structures, and lack effective feedback about the current focus. To address these limitations, we created Sasayaki (from whisper in Japanese), which augments the primary voice output with a secondary whisper of contextually relevant information, automatically or in response to user requests. It also offers new ways to jump to semantically meaningful locations. A prototype was implemented as a plug-in for an auditory Web browser. Our experimental results show that the Sasayaki can reduce the task completion times for finding elements in webpages and increase satisfaction and confidence.
