Given the auditory impressions mentioned above, we also expect that the
transitions into the closure of a labial-velar stop should correspond to those of a plain
velar stop. There is some indication that this is the case.
The F2 transition into the labial-velar stop shares the characteristics of the labial
and velar stops. The F2 transition into the labial stop drops in value, whereas the F2
transition into the velar stop remains level. The F2 transition for the labial-velar stop
exhibits a split just before closure, with one part dropping as in the labial stop and the
other part remaining level as in the velar stop.
The F4 transition into the labial-velar stop is similar to the velar one. The F4
transition into the labial stop drops in value, and the F4 transition into the velar stop and
the labial-velar stop rises.
The third issue is the question of voice onset time (VOT) for labial-velar stops.
Both Maddieson (1993, for Ewe) and Connell (1994, for Ibibio) note that the VOT of
