This has happened before. As homesick said, wrong codes punched into the automated pa voicebox in this cae though.
Happened before when a western CS pressed the CORRECT coding and the automated PA in ARABIC declared imminent ditching. The CS realised that the ARABIC pa was not the regular pattern of words. But didnt exactly know what was being said.
Transpired that there was some sort of wiring or electronic programming error on the machine. This was verified by engineering in Doha verified the same when the aircraft returned there. A7 ABS if i recall properly.
