If there is no call, the PF hands should move to the lever instantly.
Same principle for the thrust reversers.
(ps B737: I do remember 2 decades ago me pulling the speedbrake lever on rejects in case they wouldn't come out, so I'm not sure anymore if the responsibility has shifted somewhere. Even today, many PM want to arm the speedbrakes in flight I notice).
Each airline has their own procedures that have to be approved by the aviation authority in their respective country
Calling out an automatic function that works properly just adds to the workload, the PM still verifies speedbrake deployment but verbalizing it is unnecessary
It was our SOP to call ‘speedbrakes’ if they didn’t deploy, that made a lot more sense and it worked well for the years I spent at a major airline
