This study aimed to answer an ongoing validity question related to the use of nonstandard English accents in international tests of English proficiency and associated issues of test fairness. More specifically, we examined (1) the extent to which different or shared English accents had an impact on listeners' performances on the Duolingo listening…

Although intelligibility is a core concept in second language (L2) speech assessment and teaching research, the vast majority of previous work relies on audio-only stimuli. The current study set out to examine how linguistic and visual information jointly interact to determine the degree of speech intelligibility. Both first language (L1) and L2…

The current study compared five free Text-To-Speech (TTS) systems, selected based on characteristics such as availability and capabilities. Tasks were completed by 37 English learners to evaluate these systems in terms of their comprehensibility, naturalness, and intelligibility. Our findings indicate that IBM Watson and Google Translate are the…

The recorded text test (RTT) is commonly used to test dialect intelligibility, often to inform language development decisions. More than 25 papers using the RTT method were published on www.sil.org/silesr from January 2009 to March 2013. As introduced by Casad [1974. "Dialect Intelligibility Testing." Summer Institute of Linguistics…

Background: The assessment of intelligibility is an essential part of establishing the severity of a speech disorder. The intelligibility of a speaker is affected by a number of different variables relating, "inter alia," to the speech material, the listener and the listener task. Aims: To explore the impact of the number of…

Azerbaijani and Turkish are two closely-related languages from Oguz branch of Turkic languages, which are said to be mutually intelligible. Regarding this background, we designed an experiment within the framework of receptive multilingualism to investigate the role of linguistic factors in intelligibility of the Turkish language to Iranian…

Dominant notions of what constitutes a "language" and what a "dialect" within a continuum are entirely based on sociopolitical factors (i.e. the "languages by 'Ausbau'" of Kloss), totally disregarding structural and communicative aspects. This paper argues that such stance is no longer tenable in view of the modern…

Background: Newborn hearing screening, early intervention programs, and advancements in cochlear implant and hearing aid technology have greatly increased opportunities for children with hearing loss to become intelligible talkers. Optimizing speech intelligibility requires that progress be monitored closely. Although direct assessment of…

The three mainland Scandinavian languages (Danish, Swedish and Norwegian) are so closely related that the speakers mostly communicate in their own languages (semicommunication). Even though the three West Germanic languages Dutch, Frisian and Afrikaans are also closely related, semicommunication is not usual between these languages. In the present…

When understanding or evaluating foreign-accented speech, listeners are affected not only by properties of the speech itself but by their own linguistic backgrounds and their experience with different speech varieties. Given the latter influence, it is not known to what degree a diverse group of listeners might share a response to second language…
