Syllable monitoring in internally and externally generated English words

The ability of English speakers to monitor internally and externally generated words for syllables was investigated in this paper. An internal speech monitoring task required participants to silently generate a carrier word on hearing a semantically related prompt word (e.g., reveal—divulge). These productions were monitored for prespecified target strings that were either a syllable match (e.g., /dai/), a syllable mismatch (e.g., /daiv/), or unrelated (e.g., /hju:/) to the initial syllable of the word. In all three experiments the longer target sequence was monitored for faster. However, this tendency reached significance only when the longer string also matched a syllable in the carrier word. External speech versions of each experiment were run that yielded a similar influence of syllabicity but only when the syllable match string also had a closed structure. It was concluded that any influence of syllabicity found using either task reflected the properties of a shared perception-based monitoring system.
