This study investigated the impact of prolonged consonant durations on the McGurk effect and the role of static visual information in this cross-modal illusion. It was found that the McGurk effect did not break down nor diminish in strength when the consonant duration was extended up to 3.8s. This remained unchanged when the video frames in the quasi-static phase of the prolonged target consonant were substituted with copies of a single frame. Surprisingly, the McGurk effect even persisted when the visual signal in the quasi-static phase was completely removed.
