Implication

Mathematical modeling reveals phoneme recognition outperforms word scoring in children with normal and impaired hearing, indicating phoneme scores better capture intrinsic acoustical cues.

Key Points

To develop a mathematical framework that models speech discrimination scores by separating intrinsic acoustic properties from contextual and vocabulary factors.
Formulated a statistical model accounting for intrinsic sound properties, second-order acoustic and phoneme context, and vocabulary level in consonant-vowel-consonant word tests.
Applied the model to speech discrimination test data obtained from two groups of children: one normally hearing and one partially hearing.
The vocabulary factor was associated solely with age, whereas the second-order contextual factor was tied directly to high-frequency hearing loss.
The second-order contextual factor functioned primarily as an acoustical mechanism rather than a linguistic one.
Scoring tests by the percentage of recognized phonemes provided a more valid reflection of intrinsic acoustic discrimination ability than scoring by whole recognized words.
