Abstract
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.
