The conversations add new details to the final moments of the crash Monday that killed 71 people, including members of a Brazilian soccer team.
They also add further evidence supporting investigators' suspicions that the jet had depleted its fuel during its charter flight from Santa Cruz, Bolivia, to Medellin.
The audio was published in Colombian media. Brazilian soccer squad Chapecoense was on its way to the Copa Sudamericana finals in Medellin. Three players, two crew members and one journalist survived, Colombian authorities said.
CNN reported Tuesday evening that investigators were considering a shortage of fuel as a significant contributor to Monday's crash, according to a person familiar with the early stages of the inquiry.
The lack of apparent fire damage among the wreckage of the of the British Aerospace Avro RJ85 strongly suggest the jet's fuel tanks were dry when it hit the ground.
