Infant-directed (ID) speech was recorded from mothers as they interacted with their 4- to 12-month-old infants. Hierarchical regression analyses revealed that two variables, age of the mother and mother's diagnosed depression, independently accounted for significant proportions of the variance in the extent of change in fundamental frequency (ΔF0). Specifically, depressed mothers produced ID speech with smaller ΔF0 than did nondepressed mothers, and older mothers produced ID speech with larger ΔF0 than did younger mothers. Mothers who were taking antidepressant medication and who were diagnosed as being in at least partial remission produced ID speech with mean ΔF0 values that were comparable to those of nondepressed mothers. These results demonstrate explicit associations between major depressive disorder and an acoustic attribute of ID speech that is highly salient to young infants.
当母亲与4至12个月大的婴儿互动时，记录下她们的婴幼儿指向性（ID）言语。分层回归分析显示，母亲年龄和母亲被诊断出的抑郁症这两个变量独立解释了基频变化程度（ΔF0）中很大比例的方差。具体而言，抑郁的母亲所产生的ID言语的ΔF0比非抑郁的母亲小，年龄较大的母亲所产生的ID言语的ΔF0比年龄较小的母亲大。正在服用抗抑郁药物且被诊断为至少部分缓解的母亲所产生的ID言语的平均ΔF0值与非抑郁母亲的相当。这些结果表明，重度抑郁症与ID言语的一种声学属性之间存在明确关联，而这种属性对幼儿具有高度显著性。
