A note on vowel patterns in two normally developing children

The present paper reports on vowel patterns in two normally developing children, aged 1; 10–2;0 and 2;0–2;2 (years;months;days), during the period of the investigation. The study was undertaken to analyse vowel patterns not previously identified as being widespread among children (Stoel-Gammon and Dunn, 1985). Results indicated the existence of patterns involving [ai], height errors among front vowels, and resyllabification of long vowels.
