No, There Is No 150 ms Lead of Visual Speech on Auditory Speech, but a Range of Audiovisual Asynchronies Varying from Small Audio Lead to Large Audio Lag
Figure 7
Delay between visual and auditory events: (a) in the closing phase, in /aC/ where C is a plosive in the set /p t k b d g m n/; (b) in the opening phase, in /Ca/ with the same plosives.
Positive values mean that the acoustic event leads the visual one. In red: acoustic events for formants. In green: acoustic events for intensity. Signs point at mean values (over the 6 repetitions), and error bars correspond to the standard deviation.
