Then studies I've read indicate that babies babble the same initially
(at a few weeks of age), but by about 6 months the babbling has begun to
change in then direction of the sounds of the language that they hear.
What's most interesting to me is that babies begine to acquire
"supra-segemental phonemes", aka intonation patterns, around the same
age. SSPs the cues to syntax, among other things.
