Vowels in infant- and adult-directed speech

van de Weijer, Joost LU (2001) In Working Papers, Lund University, Dept. of Linguistics 49.
Abstract
F1 and F2 frequencies of the vowels /i/, /a/ and /u/ were measured in speech directed to an infant and to adults. The vowels were taken from content words as well as function words. The results showed that the vowel triangles in speech to the infant were expanded compared to those in speech to adults, but only in the content words. For function words, the opposite pattern was found: adults produced more expanded vowels in adult-directed speech than in infant-directed speech.
