1. Cross modal and linguistic interactions in speech perception
Sophie Scott, Carolyn McGettigan, Irene Altarelli, Jonas Obleser, Andy Faulkner, Stuart Rosen

2. Speech comprehension is influenced….
By concurrent visual information
By higher order linguistic information
by the acoustics of the speech signal

3. The neural basis of this varies
R 16R
Effect size (%)
Acoustic detail
30 pixels
18 pixels
6 pixels
channels C
Face and voice interaction
Predictability effects

4. Proposed study Vary these three factors within one study
Acoustic detail, facial blurring, linguistic predictability
Sparse scanning, 3X2X2 design (2,4,6 channels, 15 and 45 levels of Gaussian blur, and low and high predictability), plus a severe blur/continuous noise condition.
