The refrigerated storage of raw milk selects for psychrotolerant microorganisms, many of which produce peptidases and lipases. Some of these enzymes are heat resistant and are not sufficiently inactivated by pasteurisation or even ultra-high temperature (UHT) treatment. In the current study, 20 different raw cow's milk samples from single farms and dairy(More)
We describe a multilingual Open Source CALL game, CALL-SLT, which reuses speech translation technology developed using the Regulus platform to create an automatic conversation partner that allows intermediate-level language students to improve their uency. We contrast CALL-SLT with Wang's and Seneff's “translation game” system, in particular focussing on(More)
The enzymatic production of lactulose was described recently through conversion of lactose by a thermophilic cellobiose 2-epimerase from Caldicellulosiruptor saccharolyticus (CsCE). In the current study, we examined the application of CsCE for lactulose and epilactose production in milk (1.5% fat). The bioconversions were carried out in stirred reaction(More)
We describe a web-enabled serious game intended to help German-speaking beginner students of English improve their generative and auditory competence. The tool is built on top of the existing CALL-SLT platform, the architecture of which is briefly described. It offers a short course of 8 interactive lessons using a combined vocabulary of about 450 words,(More)
We present an English-L2 child learner speech corpus, produced by Swiss German-L1 students in their third year of learning English, which is currently in the process of being collected. The collection method uses a web-enabled multimodal language game implemented using the CALL-SLT platform, in which subjects hold prompted conversations with an animated(More)
We introduce Open CALL-SLT, a Web 2.0 framework which allows non-experts to design, implement and deploy online speech-enabled CALL courses. Course functionality is divided into six increasingly sophisticated levels; the lowest levels assume only basic web-literacy, while the higher ones require some acquaintance with simple software concepts like regular(More)
We present a framework, CALL-SLT Lite, which can be used by people with only very basic software skills to create interactive multimodal speech-enabled CALL games suitable for beginner/low intermediate child language learners. The games are deployed over the web and can be accessed through a normal browser, and the framework is completely(More)
We describe work carried out in the context of a project whose goal is to develop a web-enabled serious game, designed to help German-speaking beginner students of English improve their generative and auditory competence. The game, which is currently undergoing a first round of formal user testing, is intended as a self-study adjunct to normal classroom(More)
We summarise experiments carried out using a system-initiative spoken CALL system, in which permitted responses to prompts are defined using a minimal formalism based on templates and regular expressions, and describe a simple structural learning algorithm that uses annotated data to update response definitions. Using 1 927 utterances of training data, we(More)
