Reliability of prosodic cues for resolving syntactic ambiguity

Abstract

Although previous research has shown that listeners can use prosody to resolve syntactic ambiguities in spoken sentences, it is not clear whether naive, untrained speakers in experimental situations ordinarily produce the prosodic cues necessary for disambiguating such sentences. In a series of experiments, the authors found that neither professional nor untrained speakers consistently produced such prosodic cues when simply reading ambiguous sentences in a disambiguating discourse context. Speakers who were aware of the ambiguities and were told to intentionally pronounce the sentences with one meaning of the other, however, did produce sufficient prosodic cues for listeners to identify the intended meanings.
