No, not all hearing people can either! Reading lips is not something specifically that Deaf people can do, it is something that Deaf people HAVE done and sometimes need to do in order to exist and participate in a conversation where signing is not an option. Most people can not read lips, it is also virtually impossible to read lips accurately 100%.
Newborns respond to language sounds from any language, not just their own. However, by the age of one year, a baby's response to phonemes becomes more selective. They stop responding to phonemes that are absent from their own linguistic environment. (Kuhl, Williams, Lacerda, Stevens and Lindblom, 1992). Babies who are born deaf do not show phoneme sensitivity, but they show all the other stages of language development when they learn to use sign language. This shows that language development is built in to humans, and it also shows that language does not depend on speaking or hearing words.
