Confusions in the lipreading of initial consonant clusters were investigated. Responses were obtained from 275 subjects asked to identify by lipreading 32 cluster-vowel nonsense syllables spoken by three different speakers. The results indicated that the consonant clusters were highly confused in lipreading, since they were incorrectly perceived 89% of the time. The clusters were seen most frequently as single consonants followed in frequency by identification as other consonant combinations. The confusions for each stimulus cluster were tested statistically to determine whether their frequency of occurrence might be attributable to chance. The confusions found not to be attributable to chance fell into seven visually contrastive groups. Confusions among sounds produced in similar articulatory positions were prominent.
