個別化認知モデルとの相互作用を通した音韻意識の推定手法の検討

抄録

Different individual faces different difficulties during language development. Especially, when phonological awareness, which intentionally makes individuals aware of phonological units, is immature, diverse speech errors occur. For dealing with such diversity, it is important to provide support based on an understanding of the internal mechanisms of learners. In this article, we propose a system to support phonological awareness formation and confirm the system’s feasibility in the adaptation process to individual error patterns. The proposed system subjects a word-choice-based Shiritori game as a task and implements cognitive models to represent the individual’s state of phonological awareness. Based on the user’s repeated choices of words proposed by the model, the system eventually selects a valid model for estimating the user’s state. As a result of an experiment using the proposed system, we confirmed that participants’ preference for models was varied by phonological problems artificially generated by audio filters in a laboratory. This result supports the assumption that repetitive interactions with cognitive models can estimate individual problems of phonological awareness.
