In fact, approaching to stall is only measured by AOA; in Boeing case Stick shaker is triggered with AOA.
Airbus FBW normally can not be stalled, due to protection (Flight Control Computers do let you to fly close to AOA max but that is all, you cannot control airplane to fly at bigger AOA). However if Flight Control Computers (PRIMs, SECs as named for A 330) fails in some combination, then stalling is possible, but in this case stall warning is heard as "STALL, STALL".
