For the pronunciation learning as physical knowledge, an e-learning system is developed that aims at improvement by visualization and feedback to learners.
As a process in which pronunciation is controlled mainly by voluntary muscles, this series of processes is presented to learners as visualization information using VR and the possibility of improving pronunciation by the observation was investigated . We evaluated learners' state changes and transformations based on changes in pronunciation before and after learning and comprehension index by related English word interview examinations. As a result, the score of each evaluation test tended to be improved before and after learning.
