This investigation examined whether speakers produce reliable prosodic correlates to meaning across semantic domains and whether listeners use these cues to derive word meaning from novel words. Speakers were asked to produce phrases in infant‐directed speech in which novel words were used to convey one of two meanings from a set of antonym pairs (e.g., big/small). Acoustic analyses revealed that some acoustic features were correlated with overall valence of the meaning. However, each word meaning also displayed a unique acoustic signature, (...) and semantically related meanings elicited similar acoustic profiles. In two perceptual tests, listeners either attempted to identify the novel words with a matching meaning dimension (picture pair) or with mismatched meaning dimensions. Listeners inferred the meaning of the novel words significantly more often when prosody matched the word meaning choices than when prosody mismatched. These findings suggest that speech contains reliable prosodic markers to word meaning and that listeners use these prosodic cues to differentiate meanings. That prosody is semantic suggests a reconceptualization of traditional distinctions between linguistic and nonlinguistic properties of spoken language. (shrink)

Adopting a modified Stroop task, the authors tested the hypothesis that processing systems brought to bear on comprehension of emotional speech are attuned primarily to word evaluation in a low-context culture and language (i.e., in English), but they are attuned primarily to vocal emotion in a high-context culture and language (i.e., in Japanese). Native Japanese (Studies 1 and 2) and English speakers (Study 3) made a judgement of either vocal emotion or word evaluation of an emotionally spoken evaluative word. Word (...) evaluations and vocal emotions were comparable in extremity in the two languages. In support of the hypothesis, an interference effect by competing word evaluation in the vocal emotion judgement was significantly stronger in English than in Japanese. In contrast, an interference effect by competing vocal emotion in the word evaluation judgement was stronger in Japanese than in English. Implications for the cultural grounding of communication, emotion, and cognition are discussed. (shrink)
