Speech Identification

Background. The aim of this study was to investigate the individual effects of envelope enhancement and high-pass filtering (500 Hz) on word identification scores in quiet for individuals with Auditory Neuropathy. Method. Twelve individuals with Auditory Neuropathy (six males and six females) with ages ranging from 12 to 40 years participated in the study. Word identification was assessed using bi-syllabic words in each of three speech processing conditions: unprocessed, envelope-enhanced, and high-pass filtered. All signal processing was carried out using MATLAB-7. Results. Word identification scores showed a mean improvement of 18% with envelope enhanced versus unprocessed speech. No significant improvement was observed with high-pass filtered versus unprocessed speech. Conclusion. These results suggest that the compression/expansion signal processing strategy enhances speech identification scores—at least for mild and moderately impaired individuals with AN. In contrast, simple high-pass filtering (i.e., eliminating the low-frequency content of the signal) does not improve speech perception in quiet for individuals with Auditory Neuropathy.

Twenty elderly persons with hearing impairment were fit with binaural in-the-ear hearing aids and followed for a 6-month period post-fit. Several hearing-aid outcome measures were obtained at 0, 7, 15, 30, 60, 90, and 180 days post-fit. Outcome measures included (a) objective measures of benefit obtained with nonsense-syllable materials in quiet (CUNY Nonsense Syllable Test, NST) and sentences in multitalker babble (Hearing in Noise Test, HINT); (b) two subjective measures of benefit, one derived from pre-fit/post-fit comparisons on a general scale of hearing handicap (Hearing Handicap Inventory for the Elderly, HHIE) and the other based on a subjective scale of post-fit hearing-aid benefit (Hearing Aid Performance Inventory, HAPI); (c) a questionnaire on hearing-aid satisfaction; (d) an objective measure of hearing-aid use; and (e) a subjective measure of hearing-aid use. Reliability and stability of each measure were examined through repeated-measures analyses of variance, a series of test-retest correlations, and, where possible, scatterplots of the scores against their corresponding 95% critical differences. Many of the measures were found to be both reliable and stable indicators of hearing-aid outcome.

The hypothesis tested was that the type of reinforcement (with regard to the administrator and the recipient) is responsible for differentiating the efficiency of learning in humans. The first type, termed external reinforcement, is one in which the experimenter controls and the subject receives the reinforcement. The second type is self-reinforcement, i.e., the subject controls and receives the reinforcement. The third type ( internal reinforcement) reverses the subject-experimenter relationship employed in the first type. The fourth type ( alien reinforcement) occurs when the experimenter replaces the subject's role played in the second type. In Exp. I, 30 male undergraduates learned to choose as correct a nonsense syllable among four such syllables on each test card. A male graduate student served as the experimenter. Results indicated that the subjects can learn the task under the conditions of the fourth type of reinforcement as well as the first type. The fourth type was superior in its effect on learning. In Exp. II, 19 male undergraduates learned to choose one of the four meaningful words, and a female graduate student served as experimenter. Neither the second nor the third type was effective. It was concluded that the type of reinforcement in which the experimenter is reinforced by himself seems most effective in facilitating learning, due probably to some motivational factor.
