Xây dựng bộ trắc nghiệm đánh giá lời nói Việt: Nghien cuu dinh khung

Vietnamese is the official language of over 92 million people in Vietnam and nearly four million diaspora including in Australia, USA, and Canada.
To date, there are no standardised speech assessments for Vietnamese children. This paper outlines the development of the Vietnamese Speech Assessment through collaboration between researchers in Vietnam and Australia. The word list contains all Vietnamese consonants, vowels and tones in at least two words with different sequence constraints. Further, the word list was developed to be within the vocabulary range of young children, frequently used by Vietnamese people in different regions, picturable, and either a noun or verb. Picture stimuli were identified and the test was piloted with Vietnamese speakers of different ages who spoke different dialects. A score sheet was designed to include acceptable dialectal pronunciations, and to enable calculation of percentage of consonants/ vowels/ semivowels/ tones correct and presence of phonological processes. The Vietnamese Speech Assessment is currently undergoing norming and standardisation.
