Word discrimination can be measured with a picture-pointing forced-choice test using minimally contrastive pairs.

Evidence

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. The participant selected from four pictures on a computer screen. The d’ score was calculated. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2083
