Improving Pronunciation Accuracy, Stress, and Intelligibility with Digital Tools: Evidence from Speech Texter Intervention

Abstract

This study investigates the effectiveness of speech-to-text technology in enhancing students’ pronunciation skills, with a specific focus on the Speech Texter application. The research aims to investigate whether the use of this digital application can produce measurable improvements in pronunciation accuracy, stress, rhythm, and overall intelligibility among English language learners at Undergraduate level studying in 2nd Semester of BS Accounting and Finance at Hailey College of Commerce, Punjab University Lahore. 20 students were selected following the purposive sampling technique. A quasi-experimental design was used, involving 20 students who participated in a structured intervention using Speech Texter over a period of four weeks. Pre-test and post-test assessments were conducted to evaluate changes in their pronunciation performance. The results revealed a significant improvement in students’ pronunciation scores, indicating that the tool positively impacted their articulation, stress patterns, and clarity of speech. These findings suggest that integrating speech-to-text applications into language learning can provide immediate feedback, enhance learner autonomy, and support the development of more intelligible spoken English. The study recommends incorporating such digital applications into pronunciation practice as a supplementary method in ESL/EFL classrooms.
