The Cognitive and Articulatory Magic of Tongue Twisters in L2 Pronunciation

Abstract

Tongue twisters, often viewed as playful linguistic challenges, are powerful tools for improving second language (L2) pronunciation. This study explores their impact on pronunciation accuracy, articulatory speed, and phonemic awareness among 45 intermediate EFL learners over six weeks. Using a mixed-methods approach, we compared a tongue twister intervention group with a control group using traditional drills. Results showed significant improvements in pronunciation (22.4%), articulation speed (23.7%), and phonemic discrimination (71% to 88%) in the experimental group, alongside enhanced cognitive processing and reduced fossilized errors. Qualitative data highlighted increased learner motivation and self-awareness. Grounded in phonological and neurocognitive research, this article illuminates how tongue twisters engage sensorimotor integration and neuroplasticity, offering practical strategies for L2 classrooms.
