Each participant completed three conditions (NB, VOC, BAB) with the same partner. For each condition, there is one dual-channel Praat TextGrid and one dual-channel/stereo sound file (.wav) which both contain the two speakers (e.g., SpA and SpB tiers in the TextGrids). The pictures they described could be any of the three picture options for scenes Beach (B), Farm (F) and Street (S).

The speaker roles are coded in the filenames as follows: for example, F01F02BAB1S2.wav, that is, F01 is the one on the left audio channel (SpB) and F02 the one on the right audio channel (SpA) in the first multitalker babble condition while discussing the picture Street-2 (S2).
