很多导航应用都采用自然语言语音作为输入，避免了用手打字，减少了交通事故的发生。我们提出了 SpearkNav 导航系统，使用户能够通过语音描述预期路线，并支持基于线索的路线检索。 SpeakNav 包括一个路线描述语言理解模型，用于确定 POI 和沿预期路线的距离，并且它包括一个计算所需路线的有效算法。此外，SpeakNav支持基本的POI和位置搜索以及基于位置的路线导航。我们展示了SpeakNav如何在实际应用场景中准确识别用户意图并推荐合适的路线。
Many navigation applications take natural language speech as input, which avoids typing in words with their hands and decreases the occurrence of traffic accidents. We propose the SpearkNav navigation system that enables users to describe intended routes via speech and supports clue-based route retrieval. SpeakNav includes a route description language understanding model for determining POIs and distances along expected routes, and it includes an efficient algorithm to compute desired routes. In addition, SpeakNav supports basic POI and location search and location-based route navigation. We demonstrate how SpeakNav accurately recognizes users' intentions and recommends appropriate routes in real application scenarios.
