Human Factors
I was the pilot monitoring; we got vector for an ILS and prior for the FAF we began to configure the airplane and bug the approach speed; during that event the flying pilot did not scan his airspeed. I saw the airspeed began [to] drop and alerted the flying pilot; which resulted in a stick shaker and recovery. Altitude [during] that event was between 2;900 and 2;500 ft MSL.Flying pilot got distracted dealing with the anti-ice switches; meanwhile the trust levers were at idle; causing the airspeed to [drop]; which caused the stick shaker.Fly the airplane and not be distracted; use the pilot monitoring if needed. As a pilot monitoring I should have taken the controls when I saw the airspeed began to drop.
The cockpit was unsterile due to the Pilot Monitoring (PM) leading up to the event. On the ILS 12R in MSP we were assigned either 180 or 190 to the marker. I believe the PM was attempting to contact company as well as talk to ATC while on the approach. The plane needed to start being configured; and I remember not being able to call for changes due to ATC/ops communication by the PM. As we crossed the FAF I reduced the power significantly to decrease airspeed to allow for landing flaps. At the same time we broke out of the clouds. I looked up and reached to turn the anti-ice off. The PM then called out speed as my speed was on straight-in flaps 45 ref speed with the trend vector dropping 5-10 knots below. I advanced thrust 15-20%; however the speed continued to drop. I then added an additional ~30-40%. As I added thrust; the stick shaker activated briefly. Speed increased above straight-in ref speed during/immediately after the shaker. Thrust management then allowed the airspeed to return to the bugged ref speed and the approach continued to an uneventful landing.I attribute the cause of the slow speed event to an unsterile cockpit in the descent as well as distractions in the cockpit and lack of experience.This event could have been avoided by maintaining a sterile cockpit; ensuring the plane is properly set up for landing prior to the approach phase as well as better attention to the aircraft state by myself.
