Top-down restoration mechanisms can enhance perception of degraded speech. Even in normal hearing, however, a large variability has been observed in how effectively individuals can benefit from these mechanisms. To investigate if this variability is partially caused by individuals' linguistic and cognitive skills, normal-hearing participants of varying ages were assessed for receptive vocabulary (Peabody Picture Vocabulary Test; PPVT-III-NL), for full-scale intelligence (Wechsler Adult Intelligence Scale; WAIS-IV-NL), and for top-down restoration of interrupted speech (with silent or noise-filled gaps). Receptive vocabulary was significantly correlated with the other measures, suggesting linguistic skills to be highly involved in restoration of degraded speech.
自上而下的恢复机制可以增强对退化语音的感知。然而，即使在听力正常的情况下，人们从这些机制中受益的有效程度也存在很大差异。为了研究这种差异是否部分由个体的语言和认知技能引起，对不同年龄的听力正常参与者进行了接受性词汇（皮博迪图片词汇测验；PPVT-III-NL）、全量表智力（韦氏成人智力量表；WAIS-IV-NL）以及对中断语音（有无声或有噪声间隙）的自上而下恢复能力的评估。接受性词汇与其他测量指标显著相关，这表明语言技能在退化语音的恢复中高度相关。
