The effects of lip rounding on voice onset time production in children acquiring Hungarian

The goal of this project was to examine the effects of lip rounding on the production of voice onset time in voiceless bilabial stops in children acquiring Hungarian as their first language. The duration of voice onset time in stops followed by or embedded between high back rounded phonologically long vowels with prominent lip protrusion are considerably longer. VOT durations in stops followed or surrounded by phonologically short front mid rounded vowels with less lip protrusion or high front unrounded vowels with no lip protrusion are shorter. Developmental trends in VOT acquisition are discussed.
