Of course there are callouts and checks that are necessary and have to be done. For example the finger-pointing procedure (PF sets cleared ALT and points at it until PM says "checked") or other selection of important items, hopefully mode-s is put to use there soon so the millions of euros we had to spend to put it in have at least some use.
But at least in my outfit it seems that we go the way to silent checking then acting in most cases. For example there is no verbal answer on a flap call, the pm checks speed, configuration, warnings and only then selects the called flaps, but doesn't say anything, same for gears. Actually that was introduced as a result of an IOSA audit (and the checklists were changed to cover that, for example not established at 1000ft with final flaps, min 40% N1, final speed and checklist read is an automatic go around). Same for loc/gs alive/captured. Both are not mentioned anymore except if flying raw data (which is encouraged).
Of course we have auto callouts for 500, 100, 50, 40, 30, 20, 10 ft and we do manually call out 1000ft above/below cleared altitude, however many are reminded to do that by the 900ft wailer the boeing has built in anyway.
But we never called out FMA changes, except for one single exception: if FLARE doesn't activate below 50ft RA it is wise to do a callout to protect your own back.
