诸如虚拟个人助理之类的基于语音的交互系统不可避免地使用复杂的体系结构，其中多个模块串联(或不经常并行)来执行任务(例如，通过对话给出个性化的电影推荐)。添加模块以唤起和维持与用户的社交能力，通过模块积累的处理延迟导致相当大的话轮转换延迟。我们将增量语音处理引入到系统的生成流水线中，以克服这一挑战，只需对系统体系结构进行最小程度的更改，并根据需要解决部分不符合规范的问题。与社交电影推荐代理进行的用户研究客观上减少了话轮转换延迟；此外，用户不仅认为增量系统响应更快，而且还评价其推荐性能更高。
Speech-based interactive systems, such as virtual personal assistants, inevitably use complex architectures, with a multitude of modules working in series (or less often in parallel) to perform a task (e.g., giving personalized movie recommendations via dialog). Add modules for evoking and sustaining sociability with the user and the accumulation of processing latencies through the modules results in considerable turn-taking delays. We introduce incremental speech processing into the generation pipeline of the system to overcome this challenge with only minimal changes to the system architecture, through partial underspecification that is resolved as necessary. A user study with a sociable movie recommendation agent objectively diminishes turn-taking delays; furthermore, users not only rate the incremental system as more responsive, but also rate its recommendation performance as higher.
