A B767-300 first officer called for flaps 1 as ATC called and so the captain failed to make the flap...

Narrative:

Momentary (less than .5 second) stick shaker activation. We were turned by ATC to base leg at approximately 4;000 ft and 250 KIAS. Deployed speed brakes and landing gear in order lose energy. As airspeed decreased below maximum flap flap speed; I called for flaps 1 at the same time a radio call came in. The captain did not hear my call for flaps and I did not follow up to insure flaps were being deployed. Airspeed had decreased to approximately VMC minus 15 when a very short 'burst' of stick shaker warning was activated. Captain immediately retracted speed brakes and selected flaps 1 as I leveled the wings and added power. Normal; stabilized visual approach followed. Human factors: fatigue [it was the] end of long duty day. Complacency captain and first officer had flown together several times and trusted each other to not make mistakes. I should still verify that events I expect to take place (flaps extended) are taking place.

Title: A B767-300 First Officer called for flaps 1 as ATC called and so the Captain failed to make the flap selection. The stall warning shaker sounded momentarily as the First Officer added power and the Captain extended flaps and retracted the spoilers.
