Language learning system, language learning method and program product thereof

Abstract

The invention provides a language learning system, a language learning method and a program product thereof. The language learning system comprises a storage module, a feature extraction module and an evaluation and diagnosis module. The storage module is used for storing training corpuses and an evaluation decision tree established according to the training corpuses. The feature extraction module is used for extracting the phonetic feature of a pronunciation made by a language learner. The evaluation and diagnosis module is used for distinguishing a diagnosis path which corresponds to the pronunciation made by the language learner in the evaluation decision tree, and outputting corresponding feedback information. Therefore, the language learning system can be used for performing evaluation and feedback on characters, words or sentences made by the language learner.

Description

technical field [0001] The invention relates to a language learning system, a language learning method and a computer program product thereof. Background technique [0002] Digital language learning materials and systems developed with information technology as the main axis are attracting more and more people to join, and are also actively developing around the world. In the case of limited real teachers and geographical restrictions, learners desperately need a self-study mode that is not limited by time and region. Therefore, studying the problem of Chinese pronunciation disorders and establishing pronunciation evaluation, diagnosis and correction technologies can help create a self-study learning mode of Chinese that is not limited by time and region, and reduce learning obstacles. [0003] In order to overcome the above problems, a language learning system has been developed to provide a channel for language learners to learn by themselves. These language learning sys...

Problems solved by technology

These pronunciation assessments usually only provide weighted overall assessments and single scores or simple comparison results, and learners cannot obtain sufficient error-related information and corresponding correction methods.
