 T-unit

 C-unit

MacWhinney (2000) The CHILDES Project. Part 1: The CHAT Transcription Format, p. 61, https://doi.org/10.21415/3mhn-0z89

There is a tendency in the literature to avoid the use of the term “sentence” to refer 
to the units of spoken language. To avoid this problem, researchers use the terms 
“utterance” and “c-unit” or conversational unit. The latter is defined as a main clause 
along with its dependent (subordinate or coordinate) clauses. However, when defined in 
this way, a c-unit is really not too different from a sentence. The major difference is that a 
c-unit may be incomplete and may include disfluencies, retraces, etc. which would not be 
present in written language.

 AS-unit (Analysis of Speech Unit)

Foster et al. (2000:365)

Our unit takes Hunt's T-unit as its starting point and then elaborates this 
to deal with the features characteristic of spoken data.

    An AS-unit is a single speaker's utterance consisting of an independent clause, 
or sub-clausal unit, together with any subordinate clause(s) associsated with either.
