在生命的最初几个月，婴儿只需听成年人说话就能获得有关他们母语的语音特性的信息。对美国、俄罗斯和瑞典幼儿语言输入中语音单位的声学特性进行了研究。在这三个国家，母亲对婴儿讲话时的元音发音在听觉上都比对成年人讲话时更极端，导致元音空间“伸展”。研究结果表明，对婴儿的语言输入提供了关于构成单词基石的语言单位的特别明确的信息。
In the early months of life, infants acquire information about the phonetic properties of their native language simply by listening to adults speak. The acoustic properties of phonetic units in language input to young infants in the United States, Russia, and Sweden, were examined. In all three countries, mothers addressing their infants produced acoustically more extreme vowels than they did when addressing adults, resulting in a ''stretching'' of vowel space. The findings show that language input to infants provides exceptionally well-specified information about the linguistic units that form the building blocks for words.
