Wie is er aan de beurt? De rol van spraakmelodie bij beurtwisselingen in het Nederlands
Als mensen met elkaar praten wisselen sprekers elkaar soepel af, met gemiddeld zeer korte tussenliggende pauzes. Gesprekspartners moeten daarom steeds vooruit plannen wat ze willen zeggen en wanneer ze de beurt kunnen overnemen. Spraakmelodie speelt hier hoogstwaarschijnlijk een rol bij, maar onduidelijk…
