The purpose of the study was to examine the perceptual salience of various types of phonetic, lexical, and prosodic information by examining subjects' responses to altered words in a continuous speech-shadowing task. 48 subjects shadowed a prose passage in which the word initial consonant of 14 two-syllable words was altered by either mispronouncing or deleting it. Analysis of responses showed that subjects made use of lexical stress and stressed vowel information during word recognition to cope with the altered auditory signal
