From: <I>sicola@dolphin.upenn.edu</I><BR>Date: <I>Sat, 4 Nov 2006 16:35:15 -0500</I><BR><BR>Does anyone have a reference or two that mentions typical substitutions for<BR>the theta (voiceless-th) by young L1-English children? (E.g. My three-year-old<BR>nephew said "I'm free years old!" thus substituting [f] for theta.) I'm<BR>generally looking for typical developmental substitutions, though would be<BR>interested in examples of substitutions due to speech disorders as well, as<BR>long as it's in young children. Are there commonly-cited sources showing<BR>patterned substitution, particularly of the /s/, /t/ or /f/ (or other)?<BR><BR>Again, I'm specifically looking for L1, not L2, information.<BR><BR>Thanks!<BR><BR>Laura<BR><BR><BR>--<BR>Laura Sicola<BR>University of Pennsylvania<BR>PhD Candidate<BR>Educational Linguistics<BR><BR><BR><BR></FONT></DIV></div><br clear=all><hr>Hotmail is
