When it comes to learning an additional language, it is important that teachers prepare students to communicate with different speakers, respecting and understanding the different English-accented speeches around the world. This article helps English teachers from different parts of the world embrace language variation in their lessons,…

Background: Children with speech sound disorders (SSD) are at higher risk of communication breakdown, but the impact of having an SSD may vary from child to child. Determining the severity of SSD helps speech-language therapists (SLTs) to recognise the extent of the problem and to identify and prioritise children who require intervention. Aims:…

Despite the fact that pronunciation is a vital aspect of language learning, previous research has shown that its instruction is limited in the classroom in terms of time and attention, due in part to the time constraints inherent in any curriculum. It then becomes essential for instructors to be strategic about the pronunciation features they…

Speech is extremely variable along many different dimensions. One source of variability listeners often encounter is accented speech, in which phonological units can systematically differ from the listener's native categories. This dissertation presents five experiments testing how listeners adapt to accent-based phonological variability,…

Various speech metrics have been developed to assess and monitor phonological development in young children. Process Density Index (PDI) is one such measure employed to determine the severity of phonological errors and speech intelligibility. The present study explored the utility of PDI as a measure of phonological development in 756…

Background: Imprecise articulation has a negative impact on speech intelligibility. Therefore, treatment of articulation is clinically relevant in patients with dysarthria. In order to be effective and according to the principles of motor learning, articulation therapy needs to be intensive, well organized, with adequate feedback and requires…

Whereas many scholars have emphasized the relative importance of "comprehensibility" as an ecologically valid goal for L2 speech training, testing, and development, eliciting listeners' judgments is time-consuming. Following calls for research on more efficient L2 speech rating methods in applied linguistics, and growing attention toward…

Face masks affect the transmission of speech and obscure facial cues. Here, we examine how this reduction in acoustic and facial information affects a listener's understanding of speech prosody. English sentence pairs that differed in their intonational (statement/question) and emotional (happy/sad) prosody were created. These pairs were recorded…

Pronunciation is a common topic of interest in ELT but teachers may be unsure of what features of pronunciation to prioritise, especially in multilingual classes. While research calls for explicit pronunciation instruction that focuses on improving intelligibility and comprehensibility, implementation is still a challenge. This article presents…

This paper examined whether a younger starting age of formal instruction on a foreign language is beneficial in expanding circle countries. An experimental study was designed to examine to what extent the five varieties of English language teachers are intelligible to Japanese- (JSLs) and Korean-speaking language learners (KSLs), who have…

Spoken words vary phonetically along a number of dimensions, such as duration, pitch, and vowel quality. Much of this variation is associated with social factors like the dialect, age, or gender of the speaker -- a type of variation termed 'socio-indexical'. Traditional theories of speech perception have seen this socio-indexical variation as a…

Issues of intelligibility may arise amongst English learners when acquiring new words and phrases in North American academic settings, perhaps in part due to limited linguistic data available to the learner for understanding language use patterns. To this end, this paper examines the effects of Data-Driven Learning for Pronunciation (DDLfP) on…

Background: The increasing need for speech therapy due to our ageing population raises the demand on therapeutical resources. To meet this demand, innovative delivery of speech training is required. eHealth applications may provide a solution, as intensified and prolonged training is only possible and affordable in patients' home environment.…

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…

The present study investigated Korean-accented English (KoE) intelligibility and conducted experiments in Korea, Japan, and the USA to test the benefits of listener's familiarity and identify the key phonological features of KoE. In the experiments, the participants were asked to transcribe the target (KoE) of 100 English statements each…
