The Japanese way of tea is one of the most traditional activities to treat and serve guests with “ matcha tea” The manner to serve and the procedure for making a bowl of matcha tea are assumed to be the art performance and they are called “ otemae.” Particularly, the skills of making matcha tea are one of the important factors that affect the taste of matcha tea. The purpose of this study is to develop a system to help beginners’ learning of otemae. As the first step, in this study, we investigated the sound generated by the expert when makeing the matcha tea, and the possibility of estimating each step from the sound. As a result, our method could detect each step of procedure for making matcha tea from the envelope of the sound when the expert makes a bowl of matcha tea.
