University of Glasgow researchers published in Proceedings of the Royal Society B a study using computer-generated speakers whose eye and brow movements varied while words and vocal tone stayed constant. Western European and East Asian participants consistently rated raised eyebrows and slow blinks as more confident, while lowered brows and narrowed eyes signaled doubt. The work, covered by BBC News, shows speech perception relies on facial signals beyond words.
