Non-native listeners benefit less from gestures and visible speech than native listeners during degraded speech comprehension

Drijvers, L., & Ozyurek, A. (2020). Non-native listeners benefit less from gestures and visible speech than native listeners during degraded speech comprehension. Language and Speech, 63(2), 209-220. doi:10.1177/0023830919831311.
Native listeners benefit from both visible speech and iconic gestures to enhance degraded speech comprehension (Drijvers & OzyĆ¼rek, 2017). We tested how highly proficient non-native listeners benefit from these visual articulators compared to native listeners. We presented videos of an actress uttering a verb in clear, moderately, or severely degraded speech, while her lips were blurred, visible, or visible and accompanied by a gesture. Our results revealed that unlike native listeners, non-native listeners were less likely to benefit from the combined enhancement of visible speech and gestures, especially since the benefit from visible speech was minimal when the signal quality was not sufficient.
