When we communicate face-to-face, being able to see the person we're talking to makes it easier to understand speech, especially when the acoustic signal is degraded by noise or hearing loss. We call these benefits
audiovisual speech enhancement.
Development of Audiovisual Speech Enhancement in Children
Visual speech helps in many ways. It helps us to know when to listen, fills in missing auditory speech information, and helps to separate speech from similar competing sounds. We are studying how well children at various ages can use visual speech in these different ways. Experiments examine how sensitive children are to different audiovisual cues and how much these different mechanisms contribute to individual differences in children's audiovisual speech enhancement.
