EFL Students' Perception of Using AI Text-to-Speech Apps in Learning Pronunciation

Abstract

The present study examined students' perception of using Artificial intelligence-powered text-to-speech apps (AI TTS Apps) to learn aspects of English language pronunciation. This investigation was conducted considering the extended Unified Theory of Acceptance and Use of Technology (UTAUT2). To ensure participants had prior experience using AI TTS for pronunciation, they engaged in five sessions focused on learning both segmental and suprasegmental aspects of pronunciation through a text-to-speech app. This research employed a mixed-method approach. A questionnaire was used to examine participants' perceptions of AI TTS Apps, while interviews were conducted to gain deeper insights into their experiences with AI TTS Apps. According to the results, participants positively perceived the use of AI TTS Apps in learning pronunciation. It is recommended to utilize AI Text-to-Speech Apps both within and outside pronunciation classes, due to their positive pedagogical effects.
