The speechreading of deaf individuals familiar with Cued Speech was tested with and without the benefit of cues. With cues, the subjects correctly identified nearly twice as many phonetically balanced monosyllabic words as under the non-cued condition. This difference was highly significant statistically. Analyses of speechreading scores before and after a three-day "brush-up" Cued Speech workshop revealed insignificant improvement in both the cued and non-cued conditions. An informal item analysis of responses to cued words suggested that vowel-type in general was linked to accuracy in speechreading with cues whereas consonant-type was not, that vowel-initial words were more difficult to speechread with cues than were consonant-initial items with cues, and that one vowel-related cue position was less effective in clarifying speech than were the other cued vowel positions.
