phonological reductions in motherese

[Margaret Fleck]

I'm testing an algorithm that learns word boundaries from
transcribed conversations.    A significant issue with learning
from adult speech involves variation in word form due to
phonological reductions (e.g. vowel deletions, spread of
nasalization).    Can anyone point me at concrete data about
whether child-directed, or infant-directed, speech contains
fewer phonological reductions than adult-directed speech?

I'm particularly interested in speech directed at toddlers, because
the critical issues (from my point of view) probably involve not
the initial extraction of a few important words but rather  the
transition where they learn to understand the fine details of
normal speech.

Many thanks,

Margaret Fleck (U. Illinois, Urbana-Champaign)
