The invention relates to an interactive language learning system and an interactive language learning method. A core module of the interactive language learning system comprises a feature extraction module, a voice recognition module, a pronunciation evaluation module, a rhythm detection module and a rhythm evaluation module, all of which form a pronunciation and rhythm detection module. The interactive language learning system can judge and feed back the voice input of a learner in real time, so that the learner can accurately know specific pronunciation errors, and provide the memory content by combining the feedback result and the dynamic memory curve. Therefore, the learner can improve the language level gradually and form an interactive learning style.
