Diagnosing speech sound disorder in bilingual Vietnamese-English-speaking children
Are English-only assessments sufficient?
Multilingual children suspected of having speech sound disorders (SSD) are often only assessed in
English due to challenges facing speech-language pathologists (SLPs) such as inadequate resources, lack of access to
multilingual SLPs or interpreters, and limited SLP knowledge and skill in assessing unfamiliar languages. This paper
describes the speech profiles and diagnostic decision-making for four bilingual Vietnamese-English speaking children
aged 4–6 years. When using English-only assessment all children were diagnosed with SSD. When assessed in English and
Vietnamese, only two children were diagnosed with SSD. Many mismatches could be explained by cross-linguistic transfer
and ambient phonology. These different diagnostic outcomes demonstrate that direct speech assessment in home
language(s) and English is essential for accurate diagnosis of SSD in multilingual children.
