Background: Developmental dysarthria is a motor speech impairment commonly characterized by varying levels of reduced speech intelligibility. The relationship between intelligibility deficits and acoustic vowel space among these individuals has long been noted in the literature, with evidence of vowel centralization (e.g., in English and…

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…

Speaking anxiety is a form of foreign language anxiety which may reduce students' willingness to communicate orally. Despite accent being one of the most salient aspects of speech, there has been little research to date on the relationship between non-native accent and speaking anxiety. The purpose of this study is therefore to examine English…

A growing literature highlights the need to develop communication partner-based interventions for individuals with dysarthria. Identifying listener characteristics that facilitate speech understanding is a necessary step in designing communication partner interventions. Musicianship enhances speech understanding in adverse listening conditions…

Purpose: This study aims to investigate the effects of dysphonic voice on speech intelligibility in Cantonese-speaking adults. Method: Speech recordings from three speakers with dysphonia secondary to phonotrauma and three speakers with healthy voices were presented to 30 healthy listeners (15 men and 15 women; M[subscript age] = 22.7 years) under…

Purpose: Perceptual training is a listener-targeted means for improving intelligibility of dysarthric speech. Recent work has shown that training with one talker generalizes to a novel talker of the same sex and that the magnitude of benefit is maximized when the talkers are perceptually similar. The current study expands previous findings by…

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…

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…

Although international students often report satisfaction with their studies and view Canada as being tolerant and multicultural, increasing anti-Asian sentiment triggered by the global pandemic has highlighted the importance of exploring whether international students, especially from South and East Asia, experience discrimination. This study…

Research has increasingly demonstrated that pronunciation difficulties in English can seriously affect learners' intelligibility and ability to comprehend spoken English. It is thus crucial that we find ways of helping learners of English become more intelligible. In this talk, I present compelling research evidence in support of a strategy-based…

Second language (L2) international students are frequently blamed for miscommunication and even stigmatized and marginalized due to the way they sound. However, little is known about how their accent contributes to the L2 lived experience at foreign universities. Taking a mixed methods phenomenological approach, survey (N = 306) and…

Purpose: The aim of this study was to investigate the characteristics of electrolaryngeal (EL) speech among untrained speakers to aid in its effective introduction and to identify syllables and words that are easy or difficult to pronounce. Method: A total of 21 healthy individuals who had never used an EL were included. The participants were…

Purpose: The purpose of this study was to characterize the acoustic profile and to evaluate the intelligibility of vowel productions in prelingually deafened, Mandarin-speaking children with cochlear implants (CIs). Method: Twenty-five children with CIs and 20 age-matched children with normal hearing (NH) were recorded producing a list of Mandarin…

Since the 1990s, the emphasis on intelligibility as a goal in pronunciation teaching rather than near-native or nativelike competence has been reinforced by the increasing use of English as a lingua franca. The insight of the intelligibility principle has greatly impressed researchers in China's English education, but has "very limited and…

This mixed methods retrospective analysis analyzed change using a linguistic-based approach during speech therapy among first or second-grade students with a speech sound disorder. Measures analyzed change within intelligibility, phonemic awareness, decoding, ability to apply skills, and response to IEP goals related to speech. Five schools…
