声学强调可能传达一系列微妙的话语区别，但人们对儿童如何发展这种复杂的能力知之甚少。本文首次调查了影响幼儿自发言语中声学突出性产生的因素。在制作实验中，要求 4 岁儿童描述视频中的事件，并引出 SVO 句子。研究发现，孩子们对“新”单词和“给出”但已转移到话语中更容易理解的位置的单词都更加重视声音。这种可及性的影响与最近对成人言语的研究一致。我们的结论是，到四岁时，儿童表现出像成人一样适当地使用声音突出，这表明他们对各种话语区别很敏感。
Acoustic emphasis may convey a range of subtle discourse distinctions, yet little is known about how this complex ability develops in children. This paper presents a first investigation of the factors which influence the production of acoustic prominence in young children’s spontaneous speech. In a production experiment, SVO sentences were elicited from 4 year olds who were asked to describe events in a video. Children were found to place more acoustic prominence both on ‘new’ words and on words that were ‘given’ but had shifted to a more accessible position within the discourse. This effect of accessibility concurs with recent studies of adult speech. We conclude that, by age four, children show appropriate, adult-like use of acoustic prominence, suggesting sensitivity to a variety of discourse distinctions.
