PROBLEM TO BE SOLVED: To specify whether it is suitable to support what kind of contents by which support medium, in environment where singing is performed. SOLUTION: Time difference sequence between voice output timing and ideal timing is measured (delay measurement) for each support medium, by supporting measurement by each of a plurality of support media for an object singer. It is estimated that singing support by a predetermined support amount performed by the support medium in which a distribution degree of the time difference sequence is less than a threshold, or the smallest, is a support content suitable for environment to which singing is performed at the point. When singing support is requested in singing of a musical piece, a support content corresponding to singing environment where singing is performed is extracted, and singing support by this support content, that is, singing support in which singing is stably performed under present surrounding environment, is performed.
