Concurrent talking in immersive virtual reality: on the dominance of visual speech cues

Abstract Humans are good at selectively listening to specific target conversations, even in the presence of multiple concurrent speakers. In our research, we study how auditory-visual cues modulate this selective listening. We do so by using immersive Virtual Reality technologies with spatialized au...
