Perceptual degradation of phonetic features during adaptation. a Behavioral experiment designed to test the intelligibility of consonant-vowel pairs occurring during adaptation (DA, orange) and after adaptation (AA, blue) intervals. Six consonant vowels (/pa,ta,ka,ba,da,ga/) were added to the same background noise used in the main task (Fig. 1b). Half of the CVs were uttered during adaptation (DA), and the other half were uttered after adaptation (AA). b Comparison of correctly recognized phonemes occurring during adaptation (DA) and after adaptation (AA) intervals (mean ± s.e.m. across CVs, N = 1068, ** Yate’s corrected chi-square test, p < 0.01). c Comparison of correctly recognized phonemes occurring during adaptation (DA) and after adaptation (AA) intervals for each condition separately (mean±s.e.m., N = 267, ** Yate’s corrected chi-square test, p < 0.05)
