What is L2 Sound Production

This chapter investigates the influence of visual corrective feedback (henceforth VCF) techniques on enhancing pronunciation accuracy among ESL learners (N = 40) from various countries and L1 backgrounds. Utilizing a mixed-methods approach, the research examines the efficacy of various VCF modalities, such as interactive software: Praat and YouGlish, in improving learners' pronunciation skills. Quantitative analysis involves pre- and post-assessment of pronunciation accuracy using standardized metrics. At the same time, qualitative data is gathered through learner interviews to gauge perceptions and experiences with VCF methods. The findings suggest a significant correlation between the use of VCF and enhanced vowel production accuracy. Additionally, the qualitative insights reveal positive learner attitudes towards VCF tools, highlighting their motivational and corrective influences on pronunciation improvement. This study offers several theoretical and pedagogical implications.
