There was a record of the engine state, a/c orientation, and track all of which more strongly suggested steady flight until the last minute evasive manoeuvre when proximity to the ground must have been suddenly apparent rather than any kind of erratic demands one would have expected had there been any kind of control difficulties when desperately (as it would surely have been in this scenario) trying to avoid the known imminent contact with the ground.
You really do not need to have had a voice recording to judge which was the more likely - even if there had been a recorder, the way this case has unfolded, it would have likely been declared blank or missing or something.
