I'm fairly new to the type, but wish Airbus would drop the FMA callouts. I don't see how it accomplishes much.
FMA is one of the most important things when flying Airbus FBW aircraft, that's why is also included in the "golden rules".
Reading FMA aloud accomplishes three things:
1. Forces you to actually read the FMA as opposed to just taking a glance over it.
2. You get two sensoric inputs: visual and audio (by listening to yourself speaking), so chances of getting the correct message to your brain are better.
3. It helps your PM to stay in the loop if he's temporarily heads down (reading a checklist, making MCDU entries, etc.).
