Ambiguity pervades language. One prevalent kind ofambiguity is indirect requests. For example, “My office isreally hot” could be intended not only as a complaint aboutthe temperature, but as a request to turn on the AC. How docomprehenders determine whether a speaker is making arequest? We ask whether the prosody of an utterance providesinformation about a speaker’s intentions. In a behavioralexperiment, we find that human listeners can identify whichof two utterances a speaker intended as a request, suggestingthat speakers can produce discriminable cues. We then showthat the acoustic features associated with an utterance allow aclassifier to detect the original intent of an utterance (74%accuracy). Finally, we ask which of these features predictlistener accuracy on the behavioral experiment.
