During our arrival into Houston; we heard a flap speed aural warning. Our flaps were set to 2 and our speed was approximately 220 kts for about 5 seconds. First Officer immediately disconnected the autopilot and pitched up; while I returned the flaps to 1. On the arrival; we were assigned a speed of 210 kts and told to maintain 8;000 feet. Subsequently; we were given 7;000 feet and THEN reduce to 190 kts as we approached the Runway 8R localizer. At 8;000 feet; the First Officer reduced our speed to 190 kts and called for flaps 2. After the intercept; at about 20 nm we were cleared for the Runway 8R approach. We were following a larger aircraft and hit a little wake turbulence; I was a little distracted by it. The First Officer changed the altitude to 2;000 feet and the speed accelerated past 215 kts. At the gate; we wrote up the flap overspeed in the AML with Maintenance. We debriefed the event and agreed that; in that situation; 'green' FLCH would have prevented the overspeed. For me; personally; I should have been well aware that we were above the glidepath and would accelerate in PATH. I should not have selected flaps 2 before the descent.For my First Officer; we reviewed the protections that green FLCH offers us in the descent. For me; I should have been much more proactive and aware. There is really never a need to fly so close to the aircraft limitation. We could have used flaps 1 at 190. In the future; I will be much more cognizant of my position above or below the glidepath when being vectored for the approach.
