Research has shown that children with bilateral, moderate-to-profound hearing loss experience delays and deficits in vocal…

Indicates that 18- to 20-month-old infants can detect the correspondence between auditorially and visually perceived speech; that is, they manifest some of the components related to lip-reading phenomena in adults. This demonstration of the bimodal perception of speech in infancy has important implications for social, cognitive, and linguistic…

A case study analyzed the babbling and speech production of an infant, aged 20 to 24 months, whose family members spoke Portuguese, English, and French interchangeably. Focus was on vowel production, choice of lexicon, and the relationship between babbling and speech in the interaction of his languages. The child's utterances were recorded in…
