Confirming information on displays while giving a briefing sounds good.
Airbus FCTM gives some guidance on what to include.
Problem comes when people as PF begin calling out all the things they check starting at the glareshield while performing their cockpit preparation flow.
I hear people even calling out all the pedestal checks/selections.
Your SOP should indicate to verbalize such items if it is actually required.
In most cases all this excess talk comes from this:
During training students are frequently requested to call out all things they check/select in order to make sure they are including everything required in the SOP.
This extra verbalizing should be stopped at a certain stage or students will leave training thinking it is an SOP.
