Vowel Assessment for Systems of English (VASE)

Abstract

VASE is a single word picture naming task which has been especially designed to assess vowel production in children presenting with developmental phonological disorder. The full assessment comprises 53 line drawings plus a set of transcription sheets, realisation score sheets and vowel system profiles. The transcription, scoring and vowel system profile sheets are all photocopiable. The screening assessment consists of 10 line drawings (selected from those used in the full assessment) plus transcription and score sheets. The full assessment may be administered in its entirety, recommended in complex cases presenting with moderate-severe consonant and/or vowel difficulty, or selectively depending on the results of the screener. For example, if a child shows errored realisation on one or two vowels only, it is not necessary to further assess the full range of vowels across all contexts. Rather the clinician may select those pictures which will generate additional tokens of the problem vowels highlighted by the screener.
