I can think of only a couple of instances where you won't utter the standard words.
One is when you forget or delay turning the Packs on shortly after takeoff. Just reading the line and turning the packs back on will clear the ECAM with a nod from the PF.
The other occasion is immediately after an RTO. After the a/c has been brought to a complete stop, the PF coordinates with the tower while the PNF immediately launches into ECAM actions without being prompted by the PF - time is of the essence here.
I am prepared to be enlightened with contrary opinions.
