In this research, we implemented speech education of Japanese with one of the most innovative technology, a smartphone and application that have a function of voice recognition, and tested how Japanese learners improve their pronunciation and the effectiveness of that application.
In fact, through pronunciation training with the smartphone and some feedback to Japanese learners, we realized that it is possible to do voice training in a limited amount of time.
Through this research that is subject to thirty-three Japanese learners, we found remarkable improvement of their pronunciation as a result of using the application. Particularly, this application showed an effect for one of the most difficult pronunciation “za-gyou”, that is special mora.
The smartphone and application can be used anytime, anywhere. For this reason it is easy for the learners to use and check their pronunciation.
As an artificial intelligent and education environment are built, this kind of speech training will be able to be applied to not only Japanese but also other languages. We expect researchers to develop this phonetics.
