Abstract: The spread of World Englishes has generated a need for maximizing intelligibility in speech discourse. Yet in current pedagogy teaching pronunciation is a much neglected area. In the Sri Lankan context deviations from Standard Sri Lankan English pronunciation, especially in segmental phonology, results in impairing intelligibility even amongst the local interlocutors. Utilizing the limited technology available this study constructs a short term Action Plan based on the tenets of cooperative and collaborative learning to address two selected pronunciation deviations: the nondifferentiation between /ʃ/ and /s/ and confusion of /p/ and /f/ in 20 undergraduates users of learner English. The Action Plan informs practitioners of Teaching English as a Second Language on implementing short courses which benefit learners who deviate from inner circle pronunciation.
