Eighty-eight Standard- or Southern-Thai-speaking undergraduates received structured pronunciation training and showed improved short-vowel perception, production and confidence from pre to post.
Key findings
- Perception and production accuracy improved, L1/dialect-related deviations decreased and confidence increased, but scores and effect sizes were not reported in the abstract.
Why this matters globally
The findings support explicit feedback for difficult contrasts while prioritizing intelligibility and learner agency over accent stigma.
Thai researcher contribution
A Prince of Songkla University researcher studied learners with Standard and Southern Thai language backgrounds.
Limitations to consider
No control, randomization or follow-up was used. Isolated-word practice may inflate gains and does not establish conversational intelligibility; assessor blinding is unreported.
