Who’s next?: The role of speech melody in the turn-taking system of Dutch
When we are in a conversation, how do we know exactly when to respond, and how do we manage to respond so swiftly, yet without interrupting our interlocutors? Can speech melody – in particular utterance final “boundary tones” – help us determine who will speak next, or are these cues too late in the…
