Implication

Cross-sectional study demonstrates acoustic measures accurately predict speech intelligibility in hearing-impaired adolescents, highlighting objective markers for speech assessment.

Key Points

To identify objective acoustic speech variables that reliably predict speech intelligibility in hearing-impaired adolescents.
Evaluated speech intelligibility of 37 hearing-impaired and two normally hearing adolescents using 50 normal listeners, comparing listener scores with nine acoustic variables spanning consonant production, vowel production, and prosody via regression analysis.
Cross-validated the predictive accuracy of the identified acoustic metrics in a separate cohort of 30 hearing-impaired adolescents assessed by another group of normal listeners.
Three acoustic variables yielded a multiple correlation of 0.85 with measured intelligibility, with voice-onset-time differences between /t/ and /d/ plus second-formant differences between /i/ and /c/ accounting for approximately 70% of variance.
Cross-validation demonstrated a correlation of 0.86 between predicted and measured intelligibility scores in the validation cohort.
Five of the nine acoustic variables correlated more strongly with speech intelligibility than pure-tone audiometric thresholds across the 67 hearing-impaired subjects (mean intelligibility 76%).
