In-Car Multi-Domain Spoken Dialogs: A Wizard of Oz Study
نویسندگان
چکیده
Mobile Internet access via smartphones puts demands on in-car infotainment systems, as more and more drivers like to access the Internet while driving. Spoken dialog systems support the user by less distracting interaction than visual/hapticbased dialog systems. To develop an intuitive and usable spoken dialog system, an extensive analysis of the interaction concept is necessary. We conducted a Wizard of Oz study to investigate how users will carry out tasks which involve multiple applications in a speech-only, user-initiative infotainment system while driving. Results show that users are not aware of different applications and use anaphoric expressions in task switches. Speaking styles vary and depend on type of task and dialog state. Users interact efficiently and provide multiple semantic concepts in one utterance. This sets high demands for future spoken dialog systems.

Out-of-Domain Spoken Dialogs in the Car: A WoZ Study
Mobile Internet access via smartphones puts demands on in-car infotainment systems, as more and more drivers like to access the Internet while driving. Spoken dialog systems (SDS) distract drivers less than visual/haptic-based dialog systems. However, in conversational SDSs drivers might speak utterances which are not in the domain of the SDS and thus cannot be understood. In a Wizard of Oz stu...
متن کاملA 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” domains where the user is concentrating on tasks other than the conversation, for example, when driving a car. Designing spoken dialog interfaces for such domains is extremely challenging and the data collected will help us improve the dialog system interface and performance, unders...
متن کاملFish or Fowl: A Wizard of Oz Evaluation of Dialogue Strategies in the Restaurant Domain
Recent work on evaluation of spoken dialogue systems suggests that the information presentation phase of complex dialogues is often the primary contributor to dialogue duration. This indicates that better algorithms are needed for the presentation of complex information in speech. Currently however we lack data about the tasks and dialogue strategies on which to base such algorithms. In this pa...
متن کاملUsing a Wizard of Oz as a Baseline to Determine which System Architecture is the Best for a Spoken Language Translation System
This paper is part of an extended study on system architectures, the long term aim being to determine if a unidirectional, a bidirectional or a fixed-phrase architecture is more suitable in the context of the spoken language translator in the medical domain (MedSLT). Our aim here is to compare data collected during a Wizard of Oz (WOz) experiment with data collected using a beta bidirectional v...
متن کاملUsing a Driving Simulator to Perform a Wizard-of-oz Experiment on Speech-controlled Driver Information Systems
The paper describes a driving simulator application in the context of speech-controlled driver information systems. The objective is to study how drivers interact with such a system if it allows for natural-language communication. A prototype of such a system is under development but does not yet exist. Knowledge about typical dialogs appearing in this context as well as the effects of distract...
