Abstract
Health literacy is crucial to supporting good health and is a major national goal. Audio delivery of information is becoming more popular for informing oneself. In this study, we evaluate the effect of audio enhancements in the form of information emphasis and pauses with health texts of varying difficulty and we measure health information comprehension and retention. We produced audio snippets from difficult and easy text and conducted the study on Amazon Mechanical Turk (AMT). Our findings suggest that emphasis matters for both information comprehension and retention. When there is no added pause, emphasizing significant information can lower the perceived difficulty for difficult and easy texts. Comprehension is higher (54%) with correctly placed emphasis for the difficult texts compared to not adding emphasis (50%). Adding a pause lowers perceived difficulty and can improve retention but adversely affects information comprehension.

健康素养对于支持良好的健康和实现国家战略至关重要。获取信息的音频交付变得越来越受欢迎，以告知自己。在这项研究中，我们评估了音频增强在形式为信息强调和停顿的健康文本上的效果，并测量了健康信息的理解和保留。我们在难易不同的文本上产生了音频片段，并在亚马逊 Mechanical Turk（AMT）上进行了研究。我们的研究结果表明，强调对于信息理解和保留都至关重要。没有添加停顿时，强调重要信息可以降低对于难易文本的感知难度。在难文本上，正确的强调位置可以提高理解程度（54%），而不添加强调时（50%），理解程度更高。添加停顿可以降低感知难度并提高保留，但同时也会对信息理解产生不利影响。
