Abstract

ハミングを用いた音楽検索システムにおいて,従来は音符を単位としたマッチンダ方式が主に使われてきた.それに対し,われわれは時間を単位としたマッチング万式を開発した.この方式は,マッチングをする際にハミングおよびデータベース中のオリジナル曲の,時間の単位を正規化した上でマッチングを行なうものである.この方式は,音符抽出誤りに対する耐性が高く,また,データベースのインデックス化が可能なために,高速な検索が可能である.この方式を実装した実験システムを作成し,実験の結果について報告する.The traditional approach to music retrieval systems using humming as their query is 'note-based'; series of notes are extracted from the humming and either DP matching or its alternatives are performed. However, we have developed a new 'time-based' approach whose basic concept is to normalize the time scale of the humming and the music in the database. The new method has high robustness against note extraction erros, and also high retrieval speed is achieved since indexing of the database is possible. We have built an experimental system applying the new method and the result of the preliminary experiment is shown.
