I am aware of Ken’s data in JASA [Grant, K.W., and Walden, B.E. (1996). "Evaluating the articulation index for auditory-visual consonant recognition," J. Acoust. Soc. Am.100, 2415-2424; the raw data are on http://www.wramc.amedd.army.mil/departments/aasc/avlab/datasets.htm] and of data in Steeneken’s dissertation (1992). I would appreciate any additional leads.
Thanks, -- Hannes
