Utterance-level information

[Brian Macwhinney]

Dear Bridget,
    The answer to this depends a lot on which of the 25 or so CLAN commands you wish to use.  It also depends on what you mean by “utterance-level”.  In the case of MLU, perhaps you mean that you want to compute MLU on the basis of the main tier, rather than the %mor tier.  Perhaps the transcript you have only has a main tier.  In that case, you would add the -t%mor code to work on the main tier only.  Or perhaps you really want each turn separately, and then you would use the -u switch.  Or perhaps you just want to merge across all speakers. In that case you would use the +t* switch.  If you are working with some other program, there would be still other possible configurations and ways of interpreting what you might want.

Best,
