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…

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 examined the effect of benchmarking and peer-assessment activities on second language (L2) French learners' self-assessments of accentedness, comprehensibility, and fluency. The learners, who included 25 L2 French students enrolled in a 15-week university-level French course, recorded two oral presentations at the beginning and the end…

Purpose: The aim of this study was to quantify changes in speech intelligibility in two cohorts of people with Parkinson's disease (PD; those with and without deep brain stimulation [DBS]) across a broad range of self-selected speech rate alterations in: (1) read sentences; and (2) extemporaneous speech (monologues). Method: Four speaker groups…

The practice of second language (L2) speech perception has traditionally relied on equal-interval perceptual scales and novice listeners' (NLs) impressionistic judgments of constructs such as accentedness and comprehensibility (Munro & Derwing, 2011). However, issues have surfaced with respect to how well NLs can use these scales, whether they…

This study examines language attitudes towards different varieties of English through listener judgments of speaker and speech traits; in addition, the study explores the relationship of these judgments to the intelligibility, as well as the perceived accentedness and comprehensibility, of varieties of Asian English and General American English.…

Factors that affect comprehension of accented English (e.g., Harding, 2011) have been well studied, but little research examines how listeners' proficiency affects their sensitivity to second language (L2) accent. The current study investigated the effect of test takers' English proficiency on their comprehension ratings and ability to correctly…

Canada's growing population of international students brings ethnolinguistic diversity and socioeconomic benefits to their host communities. However, students often experience social exclusion and lack of belonging, reporting little communication with local community members for many cultural, ethnic, and religious reasons. The present study,…

This study examined the role of visual cues (facial expressions and hand gestures) in second language (L2) speech assessment. University students (N = 60) at English-medium universities assessed 2-minute video clips of 20 L2 English speakers (10 Chinese and 10 Spanish speakers) narrating a personal story. They rated the speakers'…

There is emerging evidence that collocation use plays a primary role in determining various dimensions of L2 oral proficiency assessment and development. The current study presents the results of three experiments which examined the relationship between the degree of association in collocation use (operationalized as t scores and mutual…
