Description

  The present invention relates to a karaoke scoring system for scoring the skill of singing by a user, and particularly to a system capable of scoring the skill when sung by an original artist. .

  The popular karaoke system is generally provided with a singing scoring function for scoring the skill of singing. This singing scoring function performs grading by comparing singing evaluation data such as pitch, volume, and tempo extracted from the singer's audio signal input from the microphone with reference data such as the main melody of the performance song. ing.

  In addition to such general singing grading, there is also a technique for scoring the skill of the original artist when the singer imitates the original artist for each karaoke piece (for example, Patent Document 1, Patent Document) 2).

  The technique described in Patent Document 1 has a scoring function that can give a high score to the original artist's song or an expressive song close to it, rather than simply singing karaoke music mechanically. It relates to karaoke equipment. This karaoke apparatus is configured to evaluate a user's singing by comparing singing data based on the original artist's singing and user singing voice data when the user sings karaoke music.

  The technique described in Patent Document 2 relates to a karaoke apparatus that scores how much a singer's singing voice reflects how close to the original artist. This karaoke apparatus is configured to perform singing scoring by detecting the frame energy of the singer and the frame energy of the original artist. That is, in the technique described in Patent Document 2, both frame energies are quantized and compared, and the score is calculated and displayed based on the comparison.

JP-A-10-149184 JP-A-9-16189

  As described above, when singing karaoke music, the original artist of each karaoke music is often imitated, and there is a technique for scoring the skill when singing.

  However, the singing imitation scoring technique described above creates reference data on the singing characteristics of the original artist for each karaoke song, and compares the reference data for each karaoke song with the song data obtained from the singing voice signal of the singer. By doing so, the skill of singing is scored. That is, in order to perform singing imitation scoring, reference data for singing imitation scoring must be created for each karaoke piece.

  Reference data is data that is created based on the pitch, volume, tempo, etc. of each karaoke song. It takes a lot of effort to create reference data for normal singing and reference data for singing imitation. In addition, the production cost increases.

  The present invention has been proposed in view of the above-described circumstances, and reduces the labor of creating reference data by eliminating the need to create reference data dedicated to singing karaoke for each karaoke piece in order to perform singing singing. An object of the present invention is to provide a karaoke scoring system capable of reducing the cost of creating reference data.

  The karaoke scoring system of the present invention has the following characteristic points in order to achieve the above-described object. That is, the karaoke scoring system of the present invention is a karaoke scoring system that can reflect the skill of the original artist of each karaoke song to the imitation of the singing on the scoring results in the singing scoring means, the singing reference data storing means, A singing mimic reference data storage means is provided.

  The singing standard reference data storage means is a means for storing singing standard reference data that is a singing standard for each karaoke piece. The song imitation reference data storage means is means for storing, for each original artist, song imitation reference data including the song characteristics, expression position, and expression section. The singing scoring means includes, when the user sings an arbitrary karaoke piece, singing evaluation data extracted from the user's voice signal input from the microphone, singing reference reference data of the karaoke piece, and the karaoke piece It is a means for scoring the skill of song imitation based on the song imitation reference data corresponding to the original artist.

  In addition to the above-described configuration, it is possible to provide scoring result display control means for displaying a scoring result after the expression position and expression section of the singing feature included in at least the mimicry reference data are completed.

  In the karaoke scoring system having such a configuration, for each karaoke piece, reference data that is a singing standard is created for the pitch, voice volume, tempo, etc., and stored by the function of the singing standard reference data storage means. Further, for each original artist, song mimic reference data including the singing characteristics, expression position and expression section is created and stored by the function of the song mimic reference data storage means. Singing imitation reference data is composed by describing the relationship with the reference note data, such as vibrato tendency, sharp tendency, flat tendency, tame, running, fall, etc., about the song of the original artist .

  Then, when the user performs an instruction operation for singing the karaoke song and sings the karaoke song, the singing evaluation function extracts the singing evaluation data extracted from the user's voice signal and the singing reference reference of the karaoke song. The skill of singing is scored based on the data and singing reference data corresponding to the original artist of the karaoke song. Moreover, the function of the scoring result display control means can display the scoring result of the song imitation after the expression position and expression period of the singing feature included in the song imitation reference data are completed.

  According to the singing scoring system of the present invention, for each karaoke piece of music, singing standard reference data for use in normal singing scoring is created and stored, and for each original artist, singing characteristics, expression position and expression Create and store reference data for singing imitation scoring including sections. And when performing singing imitation scoring, reflect the singing characteristics, expression position, and grading criteria of the expression interval in the reference data for singing imitation of the original artist of the karaoke composition to the singing reference reference data of each karaoke composition. Then, the singing imitation scoring value is calculated.

  For this reason, in order to score a song imitation, it is only necessary to create one reference data for singing imitation for each original artist, and it is not necessary to create reference data for singing imitation for each karaoke song. Therefore, it is possible to reduce labor for constructing a system for scoring song singing and to reduce costs for data creation.
