Speech intelligibility tests and analysis of confusions and perceptual representations of Thai initial consonants
Intelligibility rhyme test of Thai initials yielding balanced confusion matrix. For normal listeners and patients, /r/ was most confusable and /w//j//p/ the least. 5 perceptual clusters: glide, glottal, nasal, aspiration, and liquid-unaspiration. SDT bias values of c of normal hearing subjects were biased for unvoiced phonemes. Hearing aids improved phoneme perception by 10% but increased unvoiced biases.
