Lipreading can evoke an immediate bias on auditory phoneme perception and it can produce an aftereffect reflecting a shift in the phoneme boundary caused by exposure to an auditory ambiguous stimulus that is combined with nonambiguous lipread speech (recalibration). Here, we tested the stability of lipread-induced recalibration over time. Aftereffects were measured directly after exposure and after 24 hours. Aftereffects dissipated quickly during testing and were not observable anymore after a 24 hours delay.
