MLU in syllables?

[Shanley Allen]

Hi Nan,

We haven't identified anything yet - just looked at a few transcripts so far with promising results, but very preliminary. So far it looks like Inuktitut morphemes are on average 2 syllables long.

I'm not asking about norms. I assume there are no norms available for Inuktitut. And I also assume that the relationship between syllables and morphemes would work different for each language. So norms for other languages would probably not be relevant for Inuktitut. 

At this point, I just would like to know if anyone else has tried to assess MLU by syllable, to learn from what they have already done. Thanks so much for the reference - it will be very helpful.

Best,
Shanley.

But you are asking about norms? Because you seem to have identified that the conversion is closer to 1:1 for Inuktitut. This seems to be a question Phon users might be able to compute for longitudinal samples in the database. I guess Brian could say whether any dataset in TalkBank is pre-syllabified. If so, one could theoretically do this on archival data.

So anyone who writes Inuktitut (98% literacy rate!) is forced to think in syllables, and native speakers of Inuktitut who are assisting in the assessment can easily transcribe the child's speech in syllabics and then simply count the number of characters in each utterance. Those same native speakers would have a very hard time dividing Inuktitut into morphemes to calculate a traditional MLU. And assessing MLU in words (as is done for Irish, for example) is uninformative for Inuktitut because it is polysynthetic and has rampant argument ellipsis so all the interesting linguistic development at early ages happens in the morphology.

I'm working with an SLP colleague to devise tests that would be suitable for assessing language delay in Inuktitut. The target user group is pediatricians who don't know Inuktitut well enough to do a morphological analysis, but want to use measures that are appropriate for the language. This idea seems a little crazy, but our preliminary results show that MLU in syllables correlates very highly with MLU in morphemes in Inuktitut data, so it might just work.
