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(More)
Ultra Wideband radios will unavoidably face/cause severe interference from/to the existing narrowband systems nearby. To avoid interference, one of effective methods is to design appropriate pulse waveform. In this paper the problem of pulse design was equal to the problem of chebyshev function approximation and Remez algorithm was used to acquire the(More)
In this demonstration we present a conversational dialog system for automobile drivers. The system provides a voicebased interface to playing music, finding restaurants, and navigating while driving. The design of the system as well as the new technologies developed will be presented. Our evaluation showed that the system is promising, achieving high task(More)
