Abstract
A system provided herein may perform automatic temporal alignment between music audio signal and lyrics with higher accuracy than ever. A non-fricative section extracting 4 extracts non-fricative sound sections, where no fricative sounds exist, from the music audio signal. An alignment portionincludes a phone modelfor singing voice capable of estimating phonemes corresponding to temporal-alignment features. The alignment portionperforms an alignment operation using as inputs temporal-alignment features obtained from a temporal-alignment feature extracting portion, information on vocal and non-vocal sections obtained from a vocal section estimating portion, and a phoneme network SN on conditions that no phonemes exist at least in non-vocal sections and that no fricative phonemes exist in non-fricative sound sections.
