A Skywest Embraer ERJ-175, registration N128SY performing flight OO-5788 from San Francisco,CA to Saint Louis,MO (USA) with 57 people on board, was enroute nearing the top of descent when the crew briefed the approach into Saint Louis with the captain being pilot monitoring and the first officer, on his second day of initial operating experience, was pilot flying. The air was smooth with no turbulence. ATC instructed the crew to give their best forward speed and cleared the flight direct to Saint Louis. The crew entered the data into the flight management system but then noticed they were already past their top of descent (at a 3 degrees descent towards Saint Louis). The captain instructed the first officer use flight level change which increased the rate of descent to 5000 fpm, the airspeed increased. The captain instructed the first officer to extend the speed brakes to avoid overspeed, however, the speed further increased.
