Abstract (in Japanese) (See Japanese page) 
(in English) Previous studies have revealed a temporal window in which human observers perceive physically desynchronized auditory and visual signals as synchronous.
This temporal window of auditory-visual integration is recalibrated after adaptation to a constant timing difference between auditory and visual signals in nonspeech.
In this study, we investigated whether this temporal recalibration occurs in speech.
Participants observed monosyllabic audio-visual speech stimuli which had constant timing difference,
and then performed the temporal order judgment.
We varied the duration of adaptation to reveal whether it affects the temporal recalibration or not.
The results suggested that the temporal recalibration for speech occurred and might be affected by the duration of adaptation and the context preceding each judgement.
