不利条件下的言语感知是一个多阶段的过程，涉及声学，认知和语言因素之间的动态相互作用。然而，先前的研究主要集中在这个复杂系统中的因素孤立。本研究的主要目的是研究加工深度和噪声的声学挑战之间的相互作用及其对噪声中言语感知过程中加工努力的影响。两个任务被用来代表不同的处理深度。语音识别任务涉及在听觉呈现后重复一个句子（高级处理），而疲劳判断任务需要主观判断说话者是否听起来很累（低级处理）。本研究的第二个目标是调查学生的动态音高线索的变化的反应是否源于困难的语言处理的语音内容的噪音或知觉新奇的效果，由于不自然的音高轮廓。在两个实验中测量了两组具有典型听力的年轻成年人的任务诱发的瞳孔峰值反应。这两个任务（语音识别和疲劳判断）在两个实验中实施，并提出了刺激与背景噪声在实验1和无噪声在实验2。增加的峰值瞳孔扩张与更深的处理相关（即，语音识别任务），特别是在存在背景噪声的情况下。重要的是，噪声和任务之间存在非加性相互作用，如与疲劳判断任务相比，语音识别任务中对噪声的瞳孔放大峰值升高所示。此外，峰值瞳孔扩张数据表明动态音高变化引起的感知新奇效应增加，而不是反映在噪声中的语音内容的费力的语言处理。这些研究结果扩展了当前的理论，在不利条件下的言语感知表明，处理努力的水平由一个听众所花费的声学挑战和语言处理的深度之间的相互作用的影响。该研究还为未来的工作提供了基础，以研究这种复杂的相互作用对经历听力和认知挑战的临床人群的影响。
Speech perception under adverse conditions is a multistage process involving a dynamic interplay among acoustic, cognitive, and linguistic factors. Nevertheless, prior research has primarily focused on factors within this complex system in isolation. The primary goal of the present study was to examine the interaction between processing depth and the acoustic challenge of noise and its effect on processing effort during speech perception in noise. Two tasks were used to represent different depths of processing. The speech recognition task involved repeating back a sentence after auditory presentation (higher-level processing), while the tiredness judgment task entailed a subjective judgment of whether the speaker sounded tired (lower-level processing). The secondary goal of the study was to investigate whether pupil response to alteration of dynamic pitch cues stems from difficult linguistic processing of speech content in noise or a perceptual novelty effect due to the unnatural pitch contours. Task-evoked peak pupil response from two groups of younger adult participants with typical hearing was measured in two experiments. Both tasks (speech recognition and tiredness judgment) were implemented in both experiments, and stimuli were presented with background noise in Experiment 1 and without noise in Experiment 2. Increased peak pupil dilation was associated with deeper processing (i.e., the speech recognition task), particularly in the presence of background noise. Importantly, there is a non-additive interaction between noise and task, as demonstrated by the heightened peak pupil dilation to noise in the speech recognition task as compared to in the tiredness judgment task. Additionally, peak pupil dilation data suggest dynamic pitch alteration induced an increased perceptual novelty effect rather than reflecting effortful linguistic processing of the speech content in noise. These findings extend current theories of speech perception under adverse conditions by demonstrating that the level of processing effort expended by a listener is influenced by the interaction between acoustic challenges and depth of linguistic processing. The study also provides a foundation for future work to investigate the effects of this complex interaction in clinical populations who experience both hearing and cognitive challenges.
