# Backchannel animated icon

While the caller keeps talking, the listener chimes in with a brief mm-hm and never takes the floor. Light: the small acknowledgement bubble pops up from its tail (it swells, snaps back with a hit and settles), saying one quick mm. Strong: it says uh-huh, two pops in a row, the second smaller. The main utterance stays steady throughout.
