<DIV><FONT face=Arial size=2>Dear Ravi,</FONT></DIV>
<DIV><FONT face=Arial size=2>I suggest you read the first two chapters of D. K.
Oller, The Emergence of the Speech Capacity (Erlbaum, 2000). Chapter 2
includes "Myths about Babbling and the Tradition of Transcription".
One myth that he discusses is the one you report about deaf children's normal
babbling. I think you'll see that with a more careful description of "normal
babbling," the term does not characterize the early vocalizations of deaf
children. </FONT></DIV>

<DIV>Respected,</DIV>
<DIV> </DIV>
<DIV>Iam a student of Master of Science (Speech - Language Pathology) at All
India Institute of Speech and Hearing. INDIA. </DIV>
<DIV> </DIV>
<DIV>regarding that question of how is babbling in bilingual child, actually
speaking, babbling does not depend on any of the language. let it be L1 or L2.
I will give one example of hearing impaired children. children with congenital
hearinmg impairement also produces babbling. that is, their language
development will be normal till this babbling stage in the development of
language. here, without hearing any language only, children are able to
produce babbling. so.. babbling does not depend on any language which we use.
</DIV>
<DIV> </DIV>
<DIV>There are some studies regarding babbling in Hearing impaired children
and most of the studies says this only. </DIV>
<DIV> </DIV>
<DIV>This answer is based on my experience with children with hearing impaired
in our clinic. and this is purely my opinion, anyone can give their
suggestions. </DIV>
<DIV> </DIV>
<DIV>Regards.</DIV>
<DIV> </DIV>

<DIV style="WORD-WRAP: break-word">Dear Carol,
<DIV><BR></DIV>
<DIV>There is interesting material on bilingual babies' perception of their
two languages, which you will find reviewed in articles by Janet Werker (in
McCardle & Hoff, 2006, and Applied Psycholinguistics 2007, volume 28
(3)). (I report on it a little in an article in the
forthcoming Cambridge Handbook of Child Language, edited by Edith
Bavin.) The psycholinguistic methodologies show pretty clearly that
bilingual babies can distinguish the phonetic/ phonemic characteristics of
their two languages "prelinguistically." Whether they can reproduce
the differences reliably--again prelinguistically--is still open to
debate. But your student should know that there is debate. Our
student Ana Navarro summarized various positions in the introduction to her
dissertation, part of which is in the ISB4 volume.</DIV>

face=Times color=#001b9a size=4><SPAN style="FONT-SIZE: 16px">There are
claims to the contrary--and we think we see some movement away from
universal tendencies in production by 11 months--but we think the common
claim to hear babies babbling in different languages (bilinguals, or
monolinguals in different languages) depends on a combination of expectation
on the part of the hearer and the production of early words interspersed in
the babbling, which persists for quite some
time. </SPAN></FONT></DIV>

style="FONT-SIZE: 16px">Ana's experiment used early words produced by
children 26 months old, and with children that old, listeners were barely
able to distinguish the language the child was using when they didn't have
the lexical information to guide them. That is not prelinguistic and
it doesn't mean that there might not be some nascent tendencies toward
differentiation in the acoustics of the speech signal, but the ears *of
people who don't know which language they are hearing* don't reliably pick
the differences out. (Until computers, it was hard to remove language
context in the tapes people used for the studies.) In words (again not
babbling), we and others have noted some intrusion of one language in the
other, but apparently much less than in the popular idea illustrated in your
example. There are also dominance patterns, as you mention, so some
children, even simultaneous bilinguals, do show the patterns of only one
language. Ana worked with Spanish and English, which may be more
similar than French and Chinese, but they are nonetheless rhythmically very
different. </SPAN></FONT></DIV>

<DIV style="MARGIN: 0px">After a discussion of the influence of local
language on babbling, a student asked whether anything was known about
babbling in babies who heard two languages regularly. Would they show both
influences, e.g., produce French sounds with Chinese tonal differences?
Settle for one of the languages? Does anybody have a clue? Many thanks for
any information (or reassurance that we don't really know much about
it).<SPAN> </SPAN></DIV>
