Praat is a freeware program widely used by phoneticians for acoustic analyses of speech sounds, though less commonly so for pedagogical purposes. To our knowledge, no research on English pronunciation teaching has used Praat outside a classroom setting. In this article, we would like to report on a voluntary pronunciation-training project and discuss the extent to which Praat can promote self-regulating pronunciation practice beyond the classroom. Six Thai college learners with high aspirations to improve their pronunciation skills volunteered to participate in this training. In light of the small number of participants, we were unable to conduct in-depth research to examine extensively the effectiveness of using Praat outside the classroom. However, we have gained hands-on experience from undertaking this training project, and therefore would like to share with readers how an instructor can use the Praat program to help their learners improve their pronunciation. We also discuss the strengths and weaknesses of using Praat beyond the classroom setting and highlight the roles of the instructor in assisting learners to reach their pronunciation goals.
