Officials investigating the AirAsia crash say it could take up to a month to get a complete reading of all the data retrieved from the data and voice recorders found amongst the wreckage.
The voice recorder, which should contain the final conversations that took place within the cockpit and between the pilots and air traffic control, was found close to where the data recorder was retrieved from the bottom of the Java Sea on Monday.
It is now on an Indonesian navy vessel, from where it is likely to be sent to the Indonesian capital Jakarta for analysis.
"This gives me hope that the investigation will bring clarity, because what we want to do is go through the detailed analysis of the possible root causes," said Airbus CEO Fabrice Bregier.
"We will do whatever we can to support the investigation, and make sure all lessons are drawn for the future."
Flight QZ8501 disappeared from air traffic control radar on December 28 during a flight from Surabaya in Indonesia to Singapore with 162 people on board.
No survivors have been found and 48 bodies have been recovered from the Java Sea.
