number of utterances

[Brian MacWhinney]

Dear Rui,

      Back in the 1970s, people thought that it was wrong to separate out sentences.  Instead, they focused on units such as turns and utterances.  Roger Brown did not take this approach, but Bloom and some others did.  It makes little sense to relive the debates of the 1970s on this.  Instead we just need to fix the corpora

The corpora with the most extreme problems are not Peter, but Kuczaj and Belfast.  Also, some of the corpora in the MPI collections that are not (yet) available through CHILDES.  

I try to fix the most obvious cases and this is certainly one.  However, I would only break this into two utterances and leave the okay as a final communicator on the second utterance.

The difference between comma and pause is that the comma only indicates an intonational contour, whereas the pause indicates a pause.


Best regards,

The +s"\**:" option instructs freq to look for speaker tier names only. This utterances count is dependent on three conditions:
