List of words to evaluate speech perception: recording and verification of applicability

Abstract

ABSTRACT Purpose: to record the “List of Words to Evaluate the Speech Perception of Children with Hearing Loss” which is standardized for live speech presentation and verify its clinical applicability. Methods: recording: acoustic standards were used, three recordings of each word and analysis by judges. The list was recorded in silence at 60 decibels (dB) and signal noise relation of +10 dB. Participants: 30 children in the age range from five years to 10 years and 11 months, with no auditory and language disorders. The procedure was performed in live and recorded speech. Wilcoxon’s, paired t and Spearman’s correlation coefficient tests (p-value significantly less or equal to 0.05), were applied. Results: the comparison of performance for recognition of words and phonemes between live and recorded speech resulted in a statistically significant difference (p ≤ 0.05), in all conditions analyzed. The results were higher in the silence condition. There was no statistically significant difference between the time of application in the recorded speech when compared in silence and noise (p=0.064). Conclusion: the recording and application of the procedure that analyzes recognition of phonemes and words proved to be viable in recorded speech in silence and noise.
