This study aims to discuss the test methodologies that evaluate the speech intelligibility of hearing-impaired adults using various contexts. Seven adults with severe hearing loss participated in the experiment. The context of the speech intelligibility consists of 77 pairs of one-syllable words with phonemic contrasts, 30 two-syllable words and the list of each 12 and 10 sentences. The speech intelligibility of various contexts had significant correlation, and both one-syllable words with phonemic contrasts and the sentence 1 had higher correlation than other tests. The one-syllable words with phonemic contrasts took longer to test than others, and it demanded more effort to select the pair of words. However, from the point of view of the identification of segmental difficulties, the one-syllable words with phonemic contrasts that reflected segmental factors contributing to the intelligibility was useful.
