Weather
On arrival into Houston; we encountered severe turbulence between 4000 - 5000 feet 10 miles northwest of CARCO; which is on the ILS 4 approach plate into Houston. We were at 250 knots and our speed was uncontrollable and went to 280 knots for a period of time. The Controller asked what our speed was and I responded that we were trying to get it back to 250 knots but the turbulence was making it difficult. The airplane also went past 30 degrees bank and we got the 'Bank Angle' call out. It was very rough and we gave a PIREP and wrote the airplane up when we were on the ground.A previous airplane told ATC that they encountered severe turbulence; on a previous frequency. I questioned ATC where that plane was and the Controller said he did not hear that. Other airplanes also chimed in about the severe turbulence report. Unfortunately; the Controller didn't hear and did not attempt to find out from the plane that he just switched over to another frequency to find out details. I did tell the Controller that it was the airplane who he just gave a frequency change to that reported it.
