This test contains pairs of samples. The first in each pair represents the Mix1 signal, which has had its state restored immediately after frame erasures. The second in each pair represents the Mix2 signal, which has had its erased speech replaced by the correct speech. For each pair, click on button "1" if you felt the first sounds better, button "2" if the second sounds better, or "same" if they sound the same. When you are done, click submit.
