Marilyn Vihman and I found that in children studied from 9 to 16 months, that p/b was the most frequent consonant used in "stable words" (those produced in both months 15 and 16), with a mean of 40%, across the 9 early talkers who qualified for inclusion in the analysis by producing some of the same words in both sessions. Other consonants used varied greatly by individual child, with those consonants previously established as Vocal Motor Schemes (by frequency of occurrence across sessions) for each child occurring in over 90% of stable words. <br>

Hi Susanne,<br>
The following references may help you answer your question:<br>

2. Stoel-Gammon, C. (1985). Phonetic inventories, 15-24 months: A longitudinal study.<br>
* Stoel-Gammon has several others!<br>

4. Fee, E. (1995). Segments and syllables in early language acquisition.<br>

7. de Boysson-Bardies, B., & Vihman, M. M. (1991).<br>
<br>
You may also want to look at David Ingram's work, as several of his participants were in the early stages of phonological acquisition/first words.<br>
<br>
I hope these help!<br>

Subject: phonemes in early lexicon - reference<br>
<div><div></div><div class="h5"><br>
hey there,<br>
could by any chance someone point me to research about the frequency of<br>
various phonemes in children's early lexicons? i vaguely remember that<br>
words with initial "b" are overwhelmingly frequent. but i can't find a<br>
reference - is there one?<br>
<br>
thanks a lot<br>
Suse<br>
