This study investigated the use of Artificial Intelligence (AI) models and signal detection processes to generate meaningful visual and ChatGPT-like narrative feedback on second language (L2) English intelligibility. To test the effects and perceptions of such techniques, three groups of learners (N = 90) received visual and narrative feedback…

This study evaluated the voice of a modern English text-to-speech (TTS) system in an English as a foreign language (EFL) context in terms of its speech quality, ability to be understood by L2 users, and potential for focus on specific language forms. Twenty-nine Brazilian EFL learners listened to stories and sentences, produced by a TTS voice and…

In recent decades there has been a growing interest in the use of English as a lingua franca (ELF), for example identifying the lingua franca core (LFC), or pronunciation features important for intelligibility in ELF contexts. While some analyses of course books (CBs) have shown ELF research findings are not yet reflected in these materials, few…

This research study investigates and compares the operational criteria of three native English teachers (NETs) and three non-native English teachers (NNETs) when assessing English pronunciation of Thai learners. Supposedly, all six participants had already developed their own criteria of evaluating and grading pronunciation by the time the…

This pilot study explored the instructional value and potential of a computer-mediated shadowing activity for improving English as a Second Language (ESL) learners' speech intelligibility. Prospective International Teaching Assistants (ITAs), who were enrolled in an ESL classroom communication class at a large public university, completed a…

A realistic goal of pronunciation teaching in the second language context is to acquire comfortably intelligible rather than native-like pronunciation. To establish a set of teaching and learning priorities necessary for English teachers and students whose first language is Chinese, the purposes of this study are three fold: (1) Identify the…

A questionnaire study was conducted to examine how 120 highly experienced EFL (English as a foreign language) teachers in Japan adjust their pronunciation in order to facilitate and refine their students' learning skills to approach mutual intelligibility in second language (L2) classrooms (i.e. "pronunciation-specific teacher talk").…

Over the past few decades, research has demonstrated the important role that prosody (i.e., stress, rhythm, intonation) plays in the intelligibility of speakers of English as a second language (ESL). Yet the impact of this research on teacher cognition--the beliefs and knowledge that teachers possess in relation to their classroom practices--has…

The English as an International Language (EIL) research movement that has appeared due to the increasing number of non-native speakers outnumbering the native English speakers seems to challenge some of the traditional assumptions in ELT. Within the scope of ELT curriculum development, this study aims to argue against two of the traditional…

Empirical studies are essential to improving our understanding of the relationship between accent and pronunciation teaching. However, the study of pronunciation has been marginalized within the field of applied linguistics. As a result, teachers are often left to rely on their own intuitions with little direction. Although some instructors can…
