This paper analyzes the impact of German compound words on speech recognition. It is well known that, due to an idiosyncrasy of German orthography, compound words make up a major fraction of German vocabulary. And most Out-Of-Vocabulary (OOV) compounds are composed of frequent words already in the lexicon. This paper introduces a new method for handling the(More)
The arrival of smart phones significantly impacts the automotive environment. People tend to use their mobile Internet connection manually while driving which distracts and endangers the driver's safety. In order to reduce driver distraction a speech based interface to Internet services is essential. However, before developing a speech dialog system in a(More)
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/haptic-based dialog systems. To develop an intuitive and usable spoken dialog system, an extensive analysis of the(More)
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(More)
This paper reports experimental results from a driving simulation study in order to compare different speech-based in-car human-machine interface concepts. The effects of the use of a command-based and a conversational in-car speech dialog system on usability and driver distraction are evaluated. Different graphical user interface concepts have been(More)
In this paper we present an approach for creating user interfaces from abstract representations for the automotive domain. The approach is based on transformations between different user interface abstraction levels. Existing user interface representation methods are presented and evaluated. The impact of specific requirements for automotive human-machine(More)
Due to the mobile Internet revolution, people communicate increasingly via social networks and instant messaging applications using their smartphones.
