You can generally sort out the voices based on the earlier chatter, pre-flight and during takeoff roll. This flight was short enough to capture all of that.

Incorrect, " The cockpit area audio and the three audio crew channels are recorded in both the forward and the aft installed EAFR recorders. " So 4 seperate audio channels recorded on the CVR function of the EAFR.

Given the degraded power state at that moment, the only mic powerd by the RISP will be the CAM, thus the only remaining channel being recorded on the CVR of the (forward only) EAFR. Some audio forensics will be needed to identify individual persons' words (in the final moments).

Why the secrecy?

The EAFR was read out only a week or so before the preliminary report was published. There is no such transcript yet. That transcript requires significant analysis, especially for the timeframe where recording was limited to the Cockpit Area Microphone. It will need removal of audio artefacts, noise, voice analysis for attribution, etc.
There is no secrecy. There simply is nothing to release yet as the actual investigation is just getting started with the preliminary gathering of evidence nearing completion.
