A notion of truth as applicable to events of fact-stating use (utterances) of a sentence type is arguably presupposed and required by our evaluative practices of the use of language. The truth of an utterance clearly depends on what the utterance says. This fundamental dependence seems to be captured by the schema that if an utterance u says that P , then u is true iff P . Such a schema may thu...

PURPOSE Evidence from children's spontaneous speech suggests that utterance length and utterance position may help explain why children omit grammatical morphemes in some contexts but not others. This study investigated whether increased utterance length (hence, increased grammatical complexity) adversely affects children's third person singular -s production in more controlled experimental con...

Situations where a spoken dialogue system cannot interpret a user’s utterance are a major source of frustration in humancomputer spoken dialogue. Current spoken dialogue systems generally respond with an unhelpful “I’m sorry, I didn’t understand,” or something similarly uninformative. Recent work on Targeted Help has shown that giving users more appropriate feedback makes systems easier to lear...

A relation between utterance speed and the amount articulatory behavior for each phoneme reduces is investigated on the basis of the articulatory data taken by using a magnetic sensory system. The relation between the utterance speed and the change of the utterance timing for each phoneme is also focused on. Two linear-regression models are proposed: one predicts reduced articulatory movements ...
