詩吟練習支援システム構築のための詩吟声調に関する基礎検討

摘要

本研究では詩吟練習支援システム構築のための，詩吟声調に関する基礎検討について報告する．詩吟とは日本また中国古来の漢詩・律詩などに声調（メロディ）を付けて詩を吟じるものである．詩吟教授の中で，指導者は被指導者に対して，漢詩・律詩の声調表現を豊かにするための発声練習を行う．発声練習ではコンダクタと呼ばれる電子楽器で声調を演奏し，その声調に添って被指導者が発声する．ところが，詩吟教本における独特の声調表現や指導者の直観的指導が理解の妨げとなる場合がある．このような問題を解決するために，著者は詩吟練習支援システムを提案する．提案システムでは指導者と被指導者の声調を定量的に比較・評価することが可能な練習衆境を提供する．本研究では最初の検討として，熟年指導者と中堅指導者の詩吟発声データベースの構築と節調における特徴パラメータの検討を行った．%This paper reports the fundamental research of construction for the singing training support system for Shigin which is one of the Japanese traditional singings. Shigin is sung the Japanese and Chinese literatures such as Kanshi, Ritsushi and so on along the Shigin's melody called Seicho. The trainees in Shigin are singing in training when trainer plays the melody with the conductor of electric musical instrument for Shigin. However, understanding of music scores in Shigin are very difficult to learn for trainees because there are the unique expressions in the music score and intuitive training by trainers. So trainees in Shigin are often confused to master it during the voice training. To deal the problems, the author is proposed the singing training support system for Shigin. The system will be provided the training environment for trainees to understand the differences of signal characteristics between them. As a first step the system, this paper is shown the outline of the proposed system, and then the database of Shigin is also collected the singings of the senior master and master in Shigin. And, the feature parameters are analyzed by time frequency analysis on signings of the database.
