LEARNING LANGUAGES WITH A “S L I M ” AUTOMATIC TUTOR

SLIM is a prototype interactive multimedia self-learning linguistic software for foreign language students at beginner- false beginner level. It allows students to work both in an autonomous self-directed mode or in a way of programmed learning in which the process of self-instruction is preprogrammed and monitored. In this latter mode it incorporates assessment and evaluation tools in order to behave as an automatic tutor. It is organized into three basic components: audiovisual materials; a linguistic database recording all language material in text format; the supervisor. Audiovisual materials are partially taken from commercially available courses; the linguistic database is a highly sophisticated classification of all words and utterances of the course, both in written and spoken form, from all possible linguistic aspects. The supervisor is both an attractive, enjoyable and strongly pedagogically based software that allows the user to work on language materials. The most outstanding feature of SLIM is the use of speech analysis and recognition which is a fundamental aspect of all second language learning programmes. We also assume that a learning model can be represented by a finite state automaton made up by a fixed number of possible states- corresponding to the macro and microlevels at which the student’s competence may be modelled- each one being internally constituted by the actual linguistic objects of knowledge of the language that make it up. 1
