voice generated aural warning: "don oxygen masks," intermittently announced with the cabin altitude warning horn, would have saved the day. Pilots wouldn't have to "think" and waste precious time interpreting any of the conventional aural warning bells, whistles, whalers, beeps and horns.
This type of voice generated cabin altitude warning system was included in the Lockheed L1011 TriStar which I had flown many moons ago.
