【発明の名称】音楽評価装置
Document Type and Number:
Japanese Patent JP3074693
Kind Code:
B2
Abstract:
PURPOSE:To enable music evaluation matching the evaluation standard of an expert by providing an internal or external storage means stored with accompaniment information, tutor data, and fuzzy weight data and a converting means which converts input acoustic information. CONSTITUTION:Singing information which is inputted through a microphone 3 is converted into parameters of the same dimension with the tutor data by extracting only score section data. Those parameters and tutor data are compared and the comparison result is applied to fuzzy rules of respective parameters. The degree of adaption of each fuzzy rule is weighted and composed according to the stored fuzzy data. Weighting coefficients among the fuzzy rules of the respective parameters are determined by fields of music as shown in a figure. For example, the importance of a vibrato is made high for popular ballads and the importance of a level difference is increased for rock tunes.
