Abstract
Previous research has indicated that hearing‐impaired talkers' intelligibility scores are better when sentences are used than when word lists are used as speech material in word identification tests. The speech intelligibility of 20 hearing‐impaired talkers was measured with word identification tests using isolated words (W‐22 monosyllables) and words in sentence context (CID sentences). Analysis of individual talkers' intelligibility data revealed that sentence intelligibility scores were higher than word intelligibility scores only for the better talkers and that no differences were apparent between sentence and single word intelligibility for the poorer talkers. These findings agree with the results of research with normal speech that has been degraded in intelligibility by noise or filtering and indicate that an interaction may exist between context and overall intelligibility in which only speech that has a certain degree of overall intelligibility may show further intelligibility improvement with increased contextual clues.
