After the Turkish Airlines crash in 2009, Boeing began installing a spoken low-airspeed warning system in 737 airplanes. The 777 is equipped with a low-speed warning tone, but it does not feature a spoken alert. By the time a stall warning known as a "stick shaker" activated on the Asiana flight, the pilots were unable to abort the landing.
