Language Technology (LT) based applications become more popular as technology improves. Prototyping early in the design process is critical for the development of high quality applications. It is difficult, however, to do low-fidelity prototyping (e.g. paper prototyping) of applications based on LT. One technique that has been used for this kind of(More)
This paper describes a prototype of a computer-assisted pronunciation training system called MySpeech. The interface of the MySpeech system is web-based and it currently enables users to practice pronunciation by listening to speech spoken by native speakers and tuning their speech production to correct any mispronunciations detected by the system. This(More)
Early prototyping is important for developing high-quality software. Wizard of Oz (WOZ) techniques are particularly useful for early stage evaluations of applications using Language Technology Components (LTC). However, an effective interface to support the task of the wizard is crucial. While several wizard interfaces have been built to date, most of them(More)
Prototyping early in the design process is important for the development of high-quality software. Sketches and wireframes are effective artefacts that inform the design of applications based on Graphical User Interfaces. For applications using speech and Language Technologies (LTC) the Wizard of Oz method aims to fullfil this task. In order to support the(More)
Homes are essential contexts in which to understand how technologies are used and experienced. At the same time they hold substantial challenges for conducting research, exploring novel designs, and building understanding. In this paper we review approaches to studying the home, including recent innovations and issues that should guide further(More)
While Graphical User Interfaces (GUI) still represent the most common way of operating modern computing technology, Spoken Dialog Systems (SDS) have the potential to offer a more natural and intuitive mode of interaction. Even though some may say that existing speech recognition is neither reliable nor practical, the success of recent product releases such(More)
Wearable technologies are increasingly evolving into omnipresent companions. They become smaller and less obtrusive while at the same time their list of features constantly expands. Companies such as Samsung, Jawbone and Apple have driven the technological progress, yet information and feedback on how these devices work in real-life settings, what(More)
The Wizard of Oz (WOZ) method has been used for a variety of purposes in early-stage development of dialogue systems and language technology applications, from data collection, to experimentation, prototyping and evaluation. However, software to support WOZ experimentation is often developed ad hoc for specific application scenarios. In this demo we present(More)
