Purpose: The ability to understand speech under adverse listening conditions is highly variable across listeners. Despite this, studies have found that listeners with normal hearing display consistency in their ability to perceive speech across different types of degraded speech, suggesting that, for at least these listeners, global skills may be…

It has been shown in the past that International Teaching Assistants (ITAs) struggle with phonological and communication issues in the classroom (Pickering, 1999; 2001). This issue leads to misunderstandings between ITAs and undergraduate students, frustrating them both as well as the parents of the students and the departments. However, studies…

This study investigates strategies employed by East Asian international students to cope with comprehension barriers caused by different types of English accents. While these students face a range of comprehension barriers caused by unfamiliar accented English (from both native speakers and speakers of other languages), little is known about how…

Purpose: This study explored clear speech (CS) and noise-adapted speech (NAS) intelligibility benefits for native and nonnative English listeners. It also examined how the two speaking style adaptations interact with maskers that vary from purely energetic to largely informational at different signal-to-noise ratios (SNRs). Method: Materials…

During dialogue, people reach mutual comprehension through the production of feedback markers such as "yeah" or "okay." The purpose of the current study was to determine if mental load affects feedback production, as there is currently no consensus as to how mental load constrains the way in which dialogue partners reach mutual…

This study examines L2 speakers' accent attitudes in relation to their linguistic profile and current practices, recruiting 107 multilingual postgraduate students of 34 different nationalities enrolled in leading research universities in Japan. The participants completed a survey regarding their perceptions of different English varieties in…

The rapid spread of English medium instruction (EMI) across the globe has led to a growing number of non-native lecturers teaching in English to student populations that are increasingly international. The aim of the present study was to investigate to what extent lecturers with slight or moderate Dutch accents or native British English accents…

This study investigated the relationship among intelligibility, comprehensibility, and accentedness in the speech of second language learners of Spanish of varying proficiency in instructed contexts. It conceptually replicated studies by Munro and Derwing (1995a) and Derwing and Munro (1997), who found partial independence among the three speech…

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…

Purpose: This study aimed to examine the effects of wearing a face mask on speech acoustics and intelligibility, using an acoustic-phonetic analysis of speech. In addition, the effects of speakers' behavioral modification while wearing a mask were examined. Method: Fourteen female adults were asked to read a set of words and sentences under three…

The study explores the attitudes of undergraduate Flagship students in the United States towards Arabic-accented speech in English. It examines the Familiarity Principle among these students and analyzes their attitudes based on socio-intellectual status, aesthetic quality, and dynamism of Arabic-accented speech. The study also discusses the…

This paper reports on a mixed-methods study delving into EFL students' experiences and perspectives on a text-based pedagogical chatbot. Utilizing chatbot-mediated interaction, a questionnaire survey, and focus group discussions, the study centers around the cognitive and affective domains of learning in relation to the chatbot's affordances and…

This paper extends the use of Generalizability Theory to the measurement of extemporaneous L2 speech through the lens of speech perception. Using six datasets of previous studies, it reports on "G studies"--a method of breaking down measurement variance--and "D studies"--a predictive study of the impact on reliability when…

Purpose: Listeners understand significantly more speech in noise when the talker's face can be seen (visual speech) in comparison to an auditory-only baseline (a visual speech benefit). This study investigated whether the visual speech benefit is reduced when the correspondence between auditory and visual speech is uncertain and whether any…

The global spread of English nowadays has led to a shifted role in the use of English as an international lingua franca in expanding-circle contexts like Thailand. The purpose of this study was therefore to examine Thai university students' attitudes towards their own Thai-English accent, in addition to how the notion of standard language ideology…
