Background: Intelligibility and comprehensibility in speech disorders can be assessed both perceptually and instrumentally, but a lack of consensus exists regarding the terminology and related speech measures in both the clinical and scientific fields. Aims: To draw up a more consensual definition of intelligibility and comprehensibility and to…

Purpose: This study sought to determine the minimally detectable change (MDC) of sentence intelligibility for speakers with multiple sclerosis (MS) and Parkinson's disease (PD). Method: Speakers included 78 participants consisting of 32 neurologically healthy control speakers, 30 speakers with MS, and 16 speakers with PD. All speakers were…

The present systematic review examines Glenn Fulcher's contributions, works, philosophy, and research in language testing and assessment. The data includes his published articles, book chapters, books and interviews (except the one in this special issue) relevant to language testing and assessment from 1987 to March 2022. This study is conducted…

Purpose: The aim of this research note is to introduce a new appraisal form, the Classroom Communication and Collaboration (C3) Appraisal, designed to evaluate communication and collaboration within classroom settings. Method: A comprehensive synthesis of the key skills from a broad range of publications on successful communication and…

This study tracked the development of Hong Kong's assessment practices for English pronunciation over the past four decades, with reference to the nativeness and intelligibility principles in L2 pronunciation research and pedagogy. Specifically, it evaluated changes in assessors' comments on candidates' English pronunciation performance in…

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: There is a shortage of available methods to accurately inform the developmental status of children whose cultural and linguistic backgrounds vary from the mainstream. The purpose of this review article was to describe different approaches used to support the accurate characterization of speech, language, and functional communication in…

Comprehensibility has emerged as a useful and intuitive means of globally evaluating second language (L2) speakers in many research and instructional contexts. In most cases, L2 speakers' comprehensibility is assessed by external listeners who do not engage in extensive communication with the speakers, even though the degree to which a speaker is…

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…

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…
