The review reports, citing Billot-Vasquez et al. (2020), that "emblematic gestures improved listeners’ perception of L2-accented speech and their social evaluations of the speaker when the gestures were culturally familiar". The review notes this does not directly demonstrate enhanced vocabulary learning.

"Billot-Vasquez et al. (2020) found that emblematic gestures improved listeners’ perception of L2-accented speech and their social evaluations of the speaker when the gestures were culturally familiar, whereas unfamiliar emblems reduced perceptual accuracy and ratings."
