Narrative:
There were clouds in the climb. Per our procedures I climbed through 8;000 feet at vt which was 180 KIAS on this departure. We encountered moderate turbulence climbing through about 7;000 feet. The autopilot had a tough time keeping 180 in speed mode. It was unusually slow. At about 7;800 we hit a pretty good bump and the airspeed dropped about 30 knots in a second. The autopilot disconnected; the associated clacker sounded. The stick shaker engaged and the pusher engaged with the warbler. About 5 seconds later we got a stall fail caution message that [went] away after about 6 or 7 seconds. Once we got above the tops a minute or so later; the ride smoothed out.
