VISUAL CUES AND RATER PERCEPTIONS OF SECOND LANGUAGE COMPREHENSIBILITY, ACCENTEDNESS, AND FLUENCY
Published online by Cambridge University Press: 05 August 2021
Abstract
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’ comprehensibility, accentedness, and fluency using 1,000-point sliding scales. To manipulate access to visual cues, the raters were assigned to three conditions that presented audio along with (a) the speaker’s static image, (b) a static image of a speaker’s torso with dynamic face, or (c) dynamic torso and face. Results showed that raters with access to the full video tended to perceive the speaker as more comprehensible and significantly less accented compared to those who had access to less visually informative conditions. The findings are discussed in terms of how the integration of visual cues may impact L2 speech assessment.
