A wizard of oz framework for collecting spoken human-computer dialogs

This paper describes a data collection process aimed at gathering human-computer dialogs in high-stress or "busy" do- mains where the user is concentrating on tasks other than the conversation, for example, when driving a car. Designing spo- ken dialog interfaces for such domains is extremely challenging and the data collected will help us improve the dialog system in- terface and performance, understand how humans perform these tasks with respect to stressful situations, and obtain spee ch ut- terances for extracting prosodic features. This paper desc ribes the experimental design for collecting speech data in a simu- lated driving environment.
