audio samples of 12-to-24-month-olds

[Michael Brent]

Hi Karla,

Check out the recordings (sound and transcripts) at http://lsrg.cs.wustl.edu/
--- I think they may be just what you're looking for. If you want the original
DAT tapes instead of the mpegs on the web I might be able to leng them to.

Good luck,
Michael
