This paper describes how mature NLP that has been successfully applied in the area of controlled language checking can be used to deliver intelligent CALL applications1. It describe how an autonomous, long-distance second-language learning system for advanced learners can be created. The architecture of the system consists of a multimodal user interface, a set of skill-specific learning tools, ...

This paper reports on the development and the initial evaluation of a dictation&spelling prototype exercise for second language (L2) learners of Swedish based on text-to-speech (TTS) technology. Implemented on an already existing Intelligent Computer-Assisted Language Learning (ICALL) platform, the exercise has not only served as a test case for TTS in L2 environment, but has also shown a poten...

This paper describes the Spanish ICALL system ESPADA which helps language learners to improve their syntactical knowledge. The most important parts of ESPADA for the learner are a Demonstration Module and an Analysis Module. The Demonstration Module provides animated presentation of selected grammatical information. The Analysis Module is able to parse ill-formed sentences and to give adequate ...

A dialogue-based explanation facility for Intelligent CALL (ICALL) Systems is introduced. Our prototype system, DiBEx, uses meta reasoning to build up an explanation (error) tree, given a faulty user input. It relies on correct grammar sub theories, instead of explicit error taxonomies. The system enters in a tutorial dialogue with the student, where each explanation step is based on the princi...

Talebob (Speech Bob) is a newly developed interactive CALL-tool for training Danish speech with special regard to the pronunciation of highly idiomatic phrases. Talebob is currently being tested in primary schools in Nuuk, Hafnarfjörður and Tórshavn (where Danish is taught as a L2). The purpose of the current paper is twofold. We first introduce Talebob in its publicly available version, commen...

This article describes the evolution of communication technologies, accompanying transformations in everyday communicative activity, and pedagogical possibilities these tools support in second and foreign language (L2) settings. We begin with an overview of synchronous computer-mediated communication (SCMC) and uses of the Internet to mediate intercultural communication for purposes of L2 learn...
