DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the karaoke music selecting apparatus according to the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a karaoke device in which a karaoke song selecting device according to the present invention is incorporated.
FIG. 6 is a diagram for explaining an example of FIG.

First, in the karaoke apparatus according to the present embodiment, a microphone 1 for inputting a singing voice or the like, an amplifier 2 for amplifying a singing voice from the microphone 1 and an accompaniment to be described later and flowing through a speaker 6, an infrared ray from a remote controller 10. A CD accompaniment accommodating a receiver 8 for receiving song codes by radio waves, a CD (compact disc) or LD (laser disc) in which many accompaniments are recorded, and reproducing accompaniments such as selected CDs. The unit 4, the song name search unit 7 for searching for a candidate song based on the singing voice including the melody / rhythm / song of the user input from the microphone 1 which is the feature of the present embodiment, and the remote controller 10.
The display unit 5 that displays the song code or the candidate song searched by the song name search unit 7 according to the above, and the control unit 3 that controls these, and the song name search unit 7 is a melody based on the score of the karaoke song. / Rhythm / Poetry, relative pitch ratio before and after melody and rhythm, relative length ratio before and after, and full-text search song recorded karaoke database 72, It is configured to include a search processing unit 71 that searches for a desired accompaniment music from the music selection database 72.

The record structure of the database registered in the karaoke database 72 of the song name searching section 7 is, for example, as shown in FIG. 5, a song code section 50 for storing song code numbers corresponding to song names, and a text capable of searching for the song name itself. Song name part 51 to be stored as data, and singer / lyricist / composer /
For example, a singer section 52, a lyricist section 53, a composer section 54, and an accompanying information section 55 for storing other types of accompanying information, such as the commercial type of the commercial song / the program name of the television theme song, for example, in the same manner as text data for retrieval. And a singing voice search unit 56 for selecting a song from a singing voice, which is a feature of the present invention, and the singing voice search unit 56 is arranged before and after a pitch and a rhythm (sound length) for each word of a song. It is composed of a plurality of front tone ratio sections 56 including a ratio. This front pitch ratio part 56 is a song poem
A poetry section 60 stored for each word, a pitch section 58 storing the pitch ratio with the preceding sound corresponding to one word of the poetry, and a length section 59 storing the length ratio with the preceding sound. Including and The poetry section 60 stores, for example, one word of "u", "e", "no", "ha", "tsu", "no", respectively, and the pitch section 58 stores information such as "semitone higher than the previous pitch". The length section 59 stores information such as "the length is 1/2 that of the previous sound". The reason why the information stored in the front sound ratio section 56 is the ratio with the previous sound will be described later.

To input data to the record of the database registered in the karaoke database 72, as shown in FIG. 4, the song name, singer name, lyric / composer name are entered based on the score of the song (step 41). Then, based on the notes and the poetry, an accurate pitch (called an absolute pitch) and a length of the note, that is, an accurate rhythm (called an absolute rhythm) are input for each word of the poetry (step 42). Based on the absolute pitch and absolute rhythm input in step 42, the ratio of the relative displacement before and after the pitch and rhythm (sound length) of each word of the poetry is calculated, and these data are shown in FIG. 5 of the music selection database. This is done by registering each item in the record. The reason for inputting the relative displacement ratio for each word based on the absolute pitch and the absolute rhythm in step 43 is that, for example, in the case of absolute pitch, it is difficult for a karaoke user to accurately utter the absolute pitch. This is because the search margin is widened in consideration of this, and even if the singing voice is not accurate, the music search is performed by the pitch of each word and the displacement before and after the rhythm.
