The present study examined the effect of intelligibility-enhancing clear speech on listeners' recall. Native (n = 57) and non-native (n = 31) English listeners heard meaningful sentences produced in clear and conversational speech, and then completed a cued-recall task. Results showed that listeners recalled more words from clearly produced sentences. Sentence-level analysis revealed that listening to clear speech increased the odds of recalling whole sentences and decreased the odds of erroneous and omitted responses. This study showed that the clear speech benefit extends beyond word- and sentence-level recognition memory to include deeper linguistic encoding at the level of syntactic and semantic information.
本研究考察了增强可理解性的清晰言语对听者回忆的影响。母语（n=57）和非母语（n=31）英语听者分别听清晰言语和会话言语下的有意义句子，然后完成提示回忆任务。结果表明，听者能从清晰言语中回忆出更多单词。句级分析显示，听清晰言语提高了回忆整句的可能性，降低了错误和遗漏反应的可能性。本研究表明，清晰言语的益处不仅延伸到词和句子层面的识别记忆，还包括更深入的句法和语义信息的语言编码。
