Recognition Ability

The redundancy between the auditory and visual recognition of consonants was studied in 100 hearing-impaired subjects who demonstrated a wide range of speech-discrimination abilities. Twenty English consonants, recorded in CV combination with the vowel /a/, were presented to the subjects for auditory, visual, and audiovisual identification. There was relatively little variation among subjects in the visual recognition of consonants. A measure of the expected degree of redundancy between an observer’s auditory and visual confusions among consonants was used in an effort to predict audiovisual consonant recognition ability. This redundancy measure was based on an information analysis of an observer’s auditory confusions among consonants and expressed the degree to which his auditory confusions fell within categories of visually homophenous consonants. The measure was found to have moderate predictive value in estimating an observer’s audiovisual consonant recognition score. These results suggest that the degree of redundancy between an observer’s auditory and visual confusions of speech elements is a determinant in the benefit that visual cues offer to that observer.

The Individual

The purpose of this research was to determine some of the effects of consonant recognition training on the speech recognition performance of hearing-impaired adults. Two groups of ten subjects each received seven hours of either auditory or visual consonant recognition training, in addition to a standard two-week, group-oriented, inpatient aural rehabilitation program. A third group of fifteen subjects received the standard two-week program, but no supplementary individual consonant recognition training. An audiovisual sentence recognition test, as well as tests of auditory and visual consonant recognition, were administered both before and ibltowing training. Subjects in all three groups significantly increased in their audiovisual sentence recognition performance, but subjects receiving the individual consonant recognition training improved significantly more than subjects receiving only the standard two-week program. A significant increase in consonant recognition performance was observed in the two groups receiving the auditory or visual consonant recognition training. The data are discussed from varying statistical and clinical perspectives.
