"Initial investigations indicate it was the co-pilot who basically spoke," Malaysia Airlines CEO Ahmad Jauhari Yahya told a news briefing.
The last message from the cockpit -- "All right, good night" -- came around the time that two of the missing plane's crucial signalling systems were switched off.
Captain Zaharie Ahmad Shah and his first officer Fariq Abdul Hamid have become a primary focus of the investigation into the fate of Flight 370, with one of the key questions being who was controlling the aircraft when the communications systems were disabled.
The last signal from the Aircraft Communications Addressing and Reporting System (ACARS) was received 12 minutes before the co-pilot's seemingly nonchalant final words.
ACARS transmits key information on a plane's condition to the ground.
The plane's transponder -- which relays radar information on the plane's location -- was switched off just two minutes after the voice message.
