Overlapping or simultaneous talk is indicated in a variety of ways.


A left bracket bridging two lines indicates a point of overlap onset, whether at the start of an utterance or later.

Separate left square brackets, one above the other on two successive lines with utterances by different speakers, indicates the same thing.

A right bracket bridging two lines indicates a point at which two overlapping utterances both end, where one ends while the other continues, or simultaneous moments in overlaps which continue.

Separate right square brackets, one above the other on two successive lines with utterances by different speakers indicates the same thing.
