Abstract

Purpose: The aim of this pilot feasibility study was to evaluate the effectiveness of the group VietSpeech SuperSpeech program targeting speech skills and home language maintenance via telepractice.
Method: In Stage 1, using a case–control design, 30 Vietnamese-English–speaking children were assessed in English and Vietnamese, and parents completed questionnaires about speech and language competency and practices. During Stage 2, children were allocated to intervention (n = 14) or control (n = 16) conditions. COVID-19 restrictions resulted in changes including nonrandom allocation. Online group intervention targeting speech, home language maintenance, and multilingualism as a superpower was delivered 1 hr/week for 8 weeks. For Stage 3, assessments were undertaken approximately 10 weeks after the pre-intervention assessment.
Results: Parents in the intervention group significantly increased encouragement of their children to speak Vietnamese. The intervention group significantly increased intelligibility in English. Growth of Vietnamese vocabulary was faster for the control group. There was a moderate effect of intervention for children's perception of being happy talking in Vietnamese and English. There was no significant mean change from pre- to post-intervention compared with the control group for measures of speech sound accuracy in Vietnamese or English, Vietnamese intelligibility, English vocabulary, or hours of Vietnamese spoken each week.
Conclusions: This study presents preliminary evidence that this 8-hr online group program targeting speech skills and home language maintenance had some impact on Vietnamese–Australian children's speech and home language maintenance. Further research involving a randomized trial is warranted.
