چکیده

The Center for Advanced Vehicular Systems (CAVS), located at Mississippi State University (MSU), is collaborating with regional automotive manufacturers such as Nissan, to advance telematics research. This paper describes work resulting from a research initiative to investigate the use of dialog systems in automotive environments, which includes in-vehicle driver as well as automotive manufacturing environments. We present recent results of an effort to develop an in-vehicle dialog prototype, preliminary to building a dialog system to assist in workforce training in automotive manufacturing. The overall system design is presented with focus on development of the semantic information needed by the natural language and dialog management modules. We describe data collection and analysis through which the information was derived. Through this process we reduced the parsing error rate by over 20% and system understanding errors to 3%.

Audio-visual SPeaker localization for car navigation systems

Human-computer interaction for in-vehicle information and navigation systems is a challenging problem because of the diverse and changing acoustic environments. It is proposed that the integration of video and audio information can significantly improve dialog system performance, since the visual modality is not impacted by acoustic noise. In this paper, we propose a robust audio-visual integra...

CHAT To Your Destination

In the past few years, we have been developing a robust, wide-coverage, and cognitive load-sensitive spoken dialog interface, CHAT (Conversational Helper for Automotive Tasks). New progress has been made to address issues related to dynamic and attention-demanding environments, such as driving. Specifically, we try to address imperfect input and imperfect memory issues through robust understand...

Natural Language Input for In-Car Spoken Dialog Systems: How Natural is Natural?

Recent spoken dialog systems are moving away from command and control towards a more intuitive and natural style of interaction. In order to choose an appropriate system design which allows the system to deal with naturally spoken user input, a definition of what exactly constitutes naturalness in user input is important. In this paper, we examine how different user groups naturally speak to an...

Evaluation of a Dialogue System in an Automotive Environment

In this paper we discuss features to enhance the usability of a spoken dialogue system (SDS) in an automotive environment. We describe the tests that were performed to evaluate those features, and the methods used to assess the test results. One of these methods is a modification of PARADISE, a framework for evaluating the performance of SDSs (Walker et al., 1998). We discuss its drawbacks for ...

Analyzing the Effects of Spoken Dialog Systems on Driving Behavior

This paper presents an evaluation of a spoken dialog system for automotive environments. Our overall goal was to measure the impact of user-system interaction on the user’s driving performance, and to determine whether adding context-awareness to the dialog system might reduce the degree of user distraction during driving. To address this issue, we incorporated context-awareness into a spoken d...
