This study investigated whether the production of prosodic focus and phrasing contrasts was modified when interlocutors could only hear each other [auditory only (AO)], compared to when they could hear and see each other [face to face (FTF)]. The prosodic characteristics of utterances produced by six talkers were examined using both acoustic and perceptual measures (ratings of the degree of focus or clarity of the statement-question contrast). The acoustic measures showed a range of differences between narrow focus and between phrasing contrasts and some of these differences were greater in the AO setting than the FTF one. The listener’s ratings of focus and phrasing showed a clear difference between the AO and FTF conditions, with perceptual attributes of both narrow focus and echoic question phrasing being rated as clearer in the AO condition. To explain these results it is proposed that talkers compensate for the lack of visual prosodic cues in the AO condition by taking extra care (relative to FTF conditions) to ensure the effective transmission of prosodic cues.
