Human lipreading abilities were investigated. A VCR (VTR) was used to display a female narrator who spoke 100 Japanese syllables. The subjects were 40 normal adults. They were assigned to one of two narrators and participated in 3 experimental sessions of 100 syllables. The result showed: (a) Although only 15% of the syllables were reported correctly, 80% of vowels and 20% of consonants were read correctly. (b) By overlooking some types of errors, such as confusion within labials, within voiced and voiceless pairs, and so forth, 35% of syllables were recognized correctly. (c) Labials were almost perfectly discriminated from non-labials. (d) Stimulus-response patterns suggested features specific to a narrator as well as some common to narrators. (e) Practice effect were found.
