Declaration of Independence reading gets perfect vocal score in Rock Band 2

Back in July, a GameSpy preview for Rock Band 2 claimed "the phoneme detection system used for the 'talkie' parts [in Rock Band] has been completely stripped and a new one has been put in place [for Rock Band 2]." Well, Harmonix definitely stripped out the old system, but it seems to have forgotten to put a new one in its place, as the new game seems to award perfect vocal points if it detects any noise during the "talkie" parts.
