This study examines the effects of task complexity on second language (L2) pronunciation accuracy and global pronunciation measures in pronunciation-unfocused tasks and assesses the relationship between acoustic and listener-based pronunciation measures. Eighty-two Catalan/Spanish learners of English performed simple and complex versions of a…

This controlled experimental study investigated the interaction of variables associated with rating the pronunciation component of high-stakes English-language-speaking tests such as IELTS and TOEFL iBT. One hundred experienced raters who were all either familiar or unfamiliar with Brazilian-accented English or Papua New Guinean Tok Pisin-accented…

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…

Intelligibility is a critically important aspect for effective oral communication. This study explored salient (important) pronunciation errors and their relative roles in the intelligibility of nonnative speech based on listener judgments. Speech samples, collected from speakers with a Turkish as a native language (L1) background, were presented…

This study investigated the effects of L2 pronunciation instruction on speech intelligibility and fluency, the relationship between intelligibility and fluency, and the extent to which utterance fluency can predict perceived fluency. Participants were 30 beginning adult EFL learners who received either segmental or suprasegmental instruction. Oral…

This study examines the effect of native "vs." non-native prosody instruction on developing interpreter trainees' speech comprehensibility in English as a foreign language (EFL) using a pretest-posttest-delayed posttest design. Twenty-three groups of 28 interpreter trainees at a University in Iran (six different branches) took part in…

Millions engage in learning a Second Language (L2) using their mobile devices with a wide range of success. Concomitantly, there exists a growing interest in research on the effects of mobile-assisted language learning and predictors of learner outcomes (e.g., Loewen et al., 2020; Sudina & Plonsky, 2023). However, few of these apps and studies…

Despite the importance that learners must place on using prosody appropriately in EIL interaction, pragmatic functions of prosody have been largely disregarded in teaching materials and classroom instruction (Nikolic, 2018). Moreover, with a recent change in classroom paradigms instigated by the global development of educational technologies and…

When it comes to paying attention to the suprasegmental features of their speech, most learners of English seem to be unaware that such phenomena as stress, pitch, duration, and pausing can be of great importance regarding mutual intelligibility. Since they carry a considerable weight of establishing an intelligible conversation, it is argued that…

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…

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 central issue in language testing is the choice of norms, and the need to reconcile notions of "standard" English with local language norms and features. Data from studies of international intelligibility indicate that some features of "standard" language descriptions, based on native-speaker language use, are not essential…

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…

In this study I investigate the impact of different characteristics of the L2 speech signal on the intelligibility of L2 speakers of English to native listeners. Three native listeners were observed and questioned as they orthographically transcribed utterances taken from connected conversational speech produced by three L2 speakers from different…

This paper examines three aspects of phonological interference observable in the speech of Puerto Rican bilinguals: (1) segmentation patterns, (2) accentual patterns, and (3) pitch patterns. Ten representative speakers, including nine students and one faculty member, were selected to read a story in the original Spanish and in English translation.…
