通过动态调整字体大小突出重点词，降低非英语母语者听读负担。
Dynamik: Syntactically-Driven Dynamic Font Sizing for Emphasis of Key Information
- 根据语法结构动态调节词语字号，强化关键信息
- 低英语水平者感知努力降低，理解感显著提升
- 适合外语学习者与实时字幕场景，易拓展至多语言
在全球化背景下，人们越来越多地使用非母语（通用语）交流。虽然非母语者常有机会聆听外语，但理解程度通常不及母语者。为辅助实时理解，日常场景中广泛使用实时字幕（如Zoom会议、YouTube视频或社交平台）。然而，同时听和读字幕会增加认知负荷。本文提出Dynamik系统，通过缩小次要词汇字号、放大重要词汇，增强句子对比度以降低认知负荷。实验表明，该方法能有效减少低英语水平用户在听读任务中的感知表现压力与努力感，并显著提升其理解感知，尤其对英语能力较弱者效果更明显。研究还探讨了该方法在其他语言中的适用性及未来改进方向。
原文摘要 · Abstract (English)
In today's globalized world, there are increasing opportunities for individuals to communicate using a common non-native language (lingua franca). Non-native speakers often have opportunities to listen to foreign languages, but may not comprehend them as fully as native speakers do. To aid real-time comprehension, live transcription of subtitles is frequently used in everyday life (e.g., during Zoom conversations, watching YouTube videos, or on social networking sites). However, simultaneously reading subtitles while listening can increase cognitive load. In this study, we propose Dynamik, a system that reduces cognitive load during reading by decreasing the size of less important words and enlarging important ones, thereby enhancing sentence contrast. Our results indicate that Dynamik can reduce certain aspects of cognitive load, specifically, participants' perceived performance and effort among individuals with low proficiency in English, as well as enhance the users' sense of comprehension, especially among people with low English ability. We further discuss our methods' applicability to other languages and potential improvements and further research directions.
