Performance of adults with hearing loss on speech recognition index with recorded and live voice material

Abstract

Introduction: Percentage of speech recognition index – is a measure of the intelligibility of speech in a fixed intensity in which the individual can repeat correctly the greatest number of words. Objective: Compare the performance in adults with hearing loss on speech recognition index search with recorded list and with live voice list. Material and Methods: 14 individuals participated in the research (28 ears) with age between 50 and 85 years, showing bilateral sensorineural hearing loss, with descending audiometric configuration. All the individuals realized the research of speech recognition index with recorded list and live-voice list through a calibrated audiometer. Results: results showed that the percentage of adults ' errors in the speech recognition index for recorded lists is smaller than for the live voice list and there is statistically significant difference for monosyllabic words in left ear (p = 0.028). Conclusion: the findings of this study show that the performance of the participants in the research of speech recognition index with recorded list is better and has less variability than that observed with the live-voice list.
