Never heard of such a thing albeit on later gen aircraft. Without having seen or heard the call you describe, perhaps given that it’s a LH propaganda piece with one of the desk pilots is could be dubbed over? Might be that the sop is to call it but they didn’t bother or it was inaudible and they wanted to present it by the book. Would be very surprised if any voice recognition system existed on the basis you speculate given the potential for unwanted interference in critical situations or indeed, if you just haven’t said it - the other pilot will be monitoring for incapacitation etc.
