We developed audio-visual materials for intermediate learners of Japanese based on the textbook used in our Japanese language course. The materials were created using OJAD (Online Japanese Accent Dictionary), which drew visual representations of the pitch patterns of the input text and generated synthesized speech. In addition, we asked two Thai learners of Japanese to evaluate the materials along with their audio and visual functions after their trial use. The learners preferred to use both functions of the materials in combination and reported on the effectiveness of the visualization of the text's pitch patterns.
