目的：探索具有特定语言障碍的儿童（SLI）对振幅调制和持续时间提示的敏感性，这对于感知上超时性语音节奏和压力模式很重要。其中21人诊断为SLI，其中21个与SLI样本相匹配，其中21个与SLI样本相匹配。所有儿童都收到了一系列非语音听觉处理任务以及标准化的语音和语言措施。回报：发现多达70％的-80％的被诊断为SLI的儿童的表现低于听觉处理中年龄匹配的第五个百分点衡量对振幅信封的灵敏度上升时间和声音持续时间的敏感性。此外，对这些线索的敏感性的个体差异也预测了语言和识字能力的独特差异，即使是控制了年龄，非语言智商和与任务有关的（注意）因素的判断。儿童，这些不是特定于短暂的，快速连续的声学提示。取而代之的是，对持续时间和振幅信封提示的敏感性似乎更强烈地预测语言和识字结果。现在，这一发现需要以英语以外的其他语言进行复制和探索。
Purpose: To explore the sensitivity of children with specific language impairment (SLI) to amplitude-modulated and durational cues that are important for perceiving suprasegmental speech rhythm and stress patterns.Method: Sixty-three children between 7 and 11 years of age were tested, 21 of whom had a diagnosis of SLI, 21 of whom were matched for chronological age to the SLI sample, and 21 of whom were matched for language age to the SLI sample. All children received a battery of nonspeech auditory processing tasks along with standardized measures of phonology and language.Results: As many as 70%-80% of children diagnosed with SLI were found to perform below the 5th percentile of age-matched controls in auditory processing tasks measuring sensitivity to amplitude envelope rise time and sound duration. Furthermore, individual differences in sensitivity to these cues predicted unique variance in language and literacy attainment, even when age, nonverbal IQ, and task-related (attentional) factors were controlled.Conclusion: Many children with SLI have auditory processing difficulties, but for most children, these are not specific to brief, rapidly successive acoustic cues. Instead, sensitivity to durational and amplitude envelope cues appear to predict language and literacy outcomes more strongly. This finding now requires replication and exploration in languages other than English.
