这项研究调查了戴纤维口罩对言语理解的影响，这是一个未被探索的话题，可以为言语产生理论提供信息。受试者在不戴面罩和不戴面罩的情况下，产生了三种说话风格(随意、清晰、积极-情绪化)。在多人交谈中，以清晰的语言表达句子时，听者对单词识别的准确率最高，而对于随意的语言(情绪化的语言准确率介于两者之间)，听者对单词的识别准确率最高。在清晰的讲话风格中，戴面具的讲话实际上比不戴面具的讲话更容易理解，这表明说话者专门针对面罩进行清晰度调整。相反，在情绪状态下，面罩言语的可理解性低于非面罩言语，而在随意条件下，没有观察到差异，这表明情绪？然后呢？休闲？演讲不是为了让听众听得懂而产生的明确意图的风格。这些发现是从自动的和有针对性的言语适应账户的角度来讨论的。
This study investigates the impact of wearing a fabric face mask on speech comprehension, an underexplored topic that can inform theories of speech production. Speakers produced sentences in three speech styles (casual, clear, positive-emotional) while in both face-masked and non-face-masked conditions. Listeners were most accurate at word identification in multi-talker babble for sentences produced in clear speech, and less accurate for casual speech (with emotional speech accuracy numerically in between). In the clear speaking style, face-masked speech was actually more intelligible than non-face-masked speech, suggesting that speakers make clarity adjustments specifically for face masks. In contrast, in the emotional condition, face-masked speech was less intelligible than non-face-masked speech, and in the casual condition, no difference was observed, suggesting that ?emotional? and ?casual? speech are not styles produced with the explicit intent to be intelligible to listeners. These findings are discussed in terms of automatic and targeted speech adaptation accounts.
