Description

  The present invention relates to a music introduction system in a karaoke intro, and more particularly to a system that can reproduce a unique music introduction narration created by a user in an introduction (prelude section) of karaoke music.

  In order to enhance the singing atmosphere when performing karaoke singing, content that narrates the introduction of karaoke songs sung by famous hosts in the prelude section before singing has gained popularity. However, since the introduction sentence narrated in the prelude section at this time is a song introduction narration previously associated with the song data of the karaoke music piece, the karaoke company introduces the introduction sentence narrated in the prelude section for each karaoke piece. Must be created and associated with each other. For this reason, an introductory sentence cannot be made to correspond to each of the enormous number of karaoke pieces stored in the current karaoke apparatus. Therefore, the current situation is that such a narration system is limited to some genres and popular karaoke songs.

  In order to solve such a problem, a technique has been disclosed in which a liner notes reflecting the performance content is generated and given narration for an arbitrary karaoke piece (see Patent Document 1). The technique described in Patent Document 1 uses the acoustic characteristics composed of a plurality of specific values indicating the volume and brightness of the karaoke music and the genre of the karaoke music, and the music introduction stored in the music introduction database. Get the data. Then, the synthesized music introduction data is output to the prelude, the interlude, and the latter section, and the name of the performer input by the user is added to a predetermined portion of the song introduction data. .

  In addition, a technique capable of reproducing narration adapted to the contents of lyrics for each karaoke piece is disclosed (see Patent Document 2). The technique described in Patent Document 2 uses the lyrics character data of karaoke music and the keyword information of song introduction data, and if the keyword information of song introduction data exists in the lyrics character data, the song Introductory data is extracted and narration audio is inserted during the prelude.
