Abstract
A signal processing method includes a first specifying step and a first modifying step. In the first specifying step, a first modification object section for a singing voice of a music is specified based on a temporal change of pitch of singing voice data representing the singing voice or a temporal change of pitch in a score of the music. In the first modifying step, a modifying process is performed to the singing voice data. The modifying process modifies at least one of the temporal change of pitch and the temporal change of volume of the singing voice in the first modification object section which is specified by the first specifying step.

A signal processing method comprising the steps of:
- specifying a first section of a singing voice of a music based on temporal change of a pitch of singing voice data representing the singing voice or temporal change of a pitch in a score of the music;
- and
- modifying the singing voice data, wherein temporal change of at least one of the pitch, a volume, and a spectral envelope of the singing voice in the first section represented by the singing voice data is modified based on the singing voice data before the modifying step.
A signal processing apparatus comprising:
- a specifying unit configured to specify a first section of a singing voice of a music based on temporal change of a pitch of singing voice data representing the singing voice or temporal change of a pitch in a score of the music;
- and
- a modification unit configured to modify at least one of the pitch, a volume, and a spectral envelope of the singing voice in the first section represented by the singing voice data based on the singing voice data before the modifying step.
