Infants exploit vowels to label objects and actions from continuous audiovisual stimuli

Abstract Before the 6-months of age, infants succeed to learn words associated with objects and actions when the words are presented isolated or embedded in short utterances. It remains unclear whether such type of learning occurs from fluent audiovisual stimuli, although in natural environments the...
