Prosodi hos fragmentariska grounding-yttranden i dialogsystem
Jens Edlund, David House och Gabriel Skantze
We will discuss the effects of prosodic features (primarily peak height and peak alignment) on the interpretation of fragmentary grounding utterances in dialogue. The presentation will include experiments where subjects judge and respond to short human-computer dialogue fragments in Swedish, as well as a number of human-human and human-computer dialogue examples. In the human-computer dialogue examples, subjects displayed a change of response behavior related to the prosodic features of the fragmentary grounding utterances. We will also discuss plans for future experiments involving longer grounding utterances in which both focal accent position and prosodic features are varied.
