Word discrimination testing uses minimal pair contrasts to reveal spectral resolution

Evidence

The CAPT was used because it is sensitive to spectral differences in hearing aid fitting algorithms (Marriage et al. 2011 ) and was known to be highly repeatable (inter-class correlation of 0.70 for test and re-test conditions; Vickers et al. 2013 ). The CAPT is a four-alternative-forced-choice monosyllabic word-discrimination test spoken by a female British English speaker. It contained ten sets of four minimally-contrastive real words; eight sets with a contrastive consonant, e.g. fat, bat, cat, mat and two sets with a contrastive vowel, e.g. cat, cot, cut, cart. β€” Dijk, Pim van, Physiology, Psychoacoustics and…, 2080
