The present study investigated which prosodic variables were perceptually salient in the interpretation of a particular English intonational contour, rise-fall-rise (L * + H L H% in Pierrehumbert's system of intonational description). A series of utterance pairs were recorded in which sentence and contour were held constant but context was varied to produce tokens of the "incredulity" and the "uncertainty" readings of the contour. From these utterances, stimuli were synthesized in which all possible combinations of four features (duration, amplitude, pitch range and spectral characteristics) from the "incredulity" reading were substituted for the corresponding features of the "uncertainty" reading. These features were selected based upon previous observations of consistent differences between productions of the two interpretations. Subjects listened to the utterances and selected one of the two meanings. ANOVA performed on the results indicated a large main effect for pitch range and a smaller one for spectral features in interpretation selection. Amplitude and duration showed no effect. It is suggested that the association of greater pitch range with incredulity can be accounted for by the previously noted tendency of listeners to associate larger pitch ranges with a greater degree of speaker involvement; conversely, the association of smaller pitch range with uncertainty can be explained as a consequence of the perception of lesser speaker involvement.
