There is demand for subjective metrics in spoken dialogue system evaluation. SERVQUAL is a service quality evaluation method developed by marketing academics. It produces a subjective measure of the gap between expectations and perceptions in five service quality dimensions common for all services. We present how the method was applied to spoken dialogue(More)
M. Turunen J. Hakulinen K.-J. Räihä E.-P. Salonen A. Kainulainen P. Prusi Speech can be an efficient and natural means for communication between humans and computers. The development of speech applications requires techniques, methodology, and development tools capable of flexible and adaptive interaction, taking into account the needs of different users(More)
In spoken dialogue applications dialogue management has conventionally been realized with a single monolithic dialogue manager implementing a comprehensive dialogue control model. We present a highly distributed system structure that enables the integration of different dialogue control approaches to handle spoken dialogues. With this structure it is(More)
Small printed antennas will replace the commonly used normal-mode helical antennas of mobile handsets and systems in the future. This paper presents a novel small planar inverted-F antenna (PIFA) which is a common PIFA in which a U-shaped slot is etched to form a dual band operation for wearable and ubiquitous computing equipment. Health issues are(More)
Ubiquitous computing is extending the use of information technology to everyday living and working environments. A problem in developing and testing these systems is the fact that they are environments. A complete environment cannot just be taken in a laboratory and tested in conventional usability tests. Here we have addressed the problem of testing such(More)
AthosMail is a multilingual spoken dialogue system for reading of e-mail messages. The key features of the application are adaptivity and the integration of different approaches for spoken interaction. The application has flexible system structure supporting multiple components for both different and same purposes. The AthosMail system includes components(More)
We present three speech-based bus timetable systems with different approaches. The first system had open user-initiative dialogues aiming at natural interaction. The user tests revealed several problems with this approach, and we developed solutions from multiple perspectives to overcome the problems. The second system focuses on task-oriented(More)
We present how robustness and adaptivity can be supported by the spoken dialogue system architecture. AthosMail is a multilingual spoken dialogue system for e-mail domain. It is being developed in the EU-funded DUMAS project. It has flexible system architecture supporting multiple components for input interpretation, dialogue management and output(More)
Mobile devices, such as smartphones and personal digital assistants, can be used to implement efficient speech-based and multimodal interfaces. Most of the systems are serverbased, and there is a need to distribute the dialogue management tasks between the terminal devices and the server. Since the technologies are not mature and the platforms are(More)
This article introduces how speech and non-speech audio can be used in ubiquitous computing office environments. We describe an iterative development of an augmented office environment that helps people in their everyday tasks in office settings. Architectural as well as interaction issues are covered in this paper. We discuss how we have addressed the(More)
