On how accent distribution can signal speaker adaptation.
Some dialogues are perceived as running more smoothly than others. To some extent that impression could be related to how well speakers adapt their prosody to each other. Adaptation in prosody can be signaled by the use of pitch accents that indicate how utterances are structurally related to those of the interlocutor (prosodic function) or by copying the interlocutor's prosodic features (prosodic form). The same acoustic features, such as pitch, are involved in both ways of adaptation. Further, function and form may require a different prosody for successful adaptation in certain discourse contexts. In this study we investigate to what extent interlocutors are perceived as good adapters, depending on whether the prosody of both speakers is functionally coherent or similar in form. This is done in two perception tests using prosodically manipulated dialogues. Results show that coherent functional prosody can be a cue for speaker adaptation and that this cue is more powerful than similarity in prosodic form.
