title: Phonetic development in early infancy: a study of four Swedish children during the first eighteen months of life.
abstract: The present paper presents data on the phonetic development of four normal Swedish infants, who were audiorecorded bi-weekly in their homes from 0;1 to 1;5. Our results show five distinct stages in the development of early vocalizations: the glottal stage, the velar/uvular stage, the vocalic stage, the reduplicated consonant babbling stage and the variegated consonant babbling stage. The results are based on auditory analysis of selected parts of the material. A comparison is made of this developmental pattern with studies of infants raised in other linguistic communities. The results of this comparison support the claim that babbling follows a universal developmental pattern.
