Gathering Corpora of Affected Speech in Human-Machine Interaction: Refinement of the Wizard-of-Oz Technique
In: Proceedings of the International Symposium on Linguistic Patterns in Spontaneous Speech (LPSS 2006). Academia Sinica, Taipei, Taiwan, pages 55--66.
The primary aim of this paper is to address the methodological desiderata in obtaining a corpus of affected speech in human-machine interaction. We propose requirements that are to be met in order that a Wizard-of-Oz scenario designed to elicit affected speech could result in ecologically valid data. In addition, we report about the Wizard-of-Oz experiment conducted in the framework of the NIMITEK project. This project has the primary goal to investigate the role of emotions and intentions in human-machine dialogue. In the first phase of the experiment the focus was on prosody as a means to communicate emotional state.
