Description

  The present invention displays the target voice volume level that the singer should utter, and compares the input voice volume level actually spoken by the singer with the target voice volume level to determine whether or not the voice can be uttered at the target voice volume level. The present invention relates to a voice volume level determination system in karaoke singing that can notify a singer.

  In karaoke singing, it can be said that it sang well by singing at a volume level suitable for each piece of music. In other words, rather than singing at almost the same volume level throughout the entire song, the volume level is increased especially in the rust part that you want to appeal to the listener, while the volume level is decreased in the part where you sing to speak carefully. Singing with a change in the volume level is the deciding factor for advanced singers. As described above, in order to sing well, the voice volume level must be controlled, but it is difficult for a user who is not yet singing to appropriately control the voice volume level. On the other hand, even if a user is good at singing, when there is a lack of practice as in the case of music sung for the first time, it may be difficult to sing at a volume level suitable for the music.

  In addition, when practicing singing, the voice volume level is objectively controlled by changing the volume of the singing voice based on the instructed voice volume level, instead of changing the voice volume level by one's own judgment. It is also true that you will be able to.

  Conventionally, a technique for calling attention to a voice volume level has been disclosed (see Patent Document 1). The technique described in this Patent Document 1 is a spontaneous and spontaneously noticed to the singer when the singing voice volume of the singer singing along with the accompaniment music is too high, without needing to pay attention to the singer again. This is a technique for reducing the singing voice volume level of a singer without giving an effective trigger for lowering the singing voice volume and thereby impairing the enjoyment of using karaoke. In other words, this karaoke performance device calculates the moving average of the amplitude level of the singing voice input from the microphone, and reduces the output volume of the accompaniment music when the calculated moving average level exceeds a preset reference level. It is like that.

  Moreover, the technique which enabled it to know sequentially the scoring result with respect to a song voice during a song is disclosed (refer patent document 2). The technique described in Patent Document 2 reproduces a performance music signal based on performance data by a performance music reproduction unit and outputs a performance music from a speaker, and based on lyrics data corresponding to the performance data by a display control unit. To display the lyrics of the performance on the karaoke display. Moreover, the singing voice signal of the singing sound for the performance music is input from the microphone, and the singing voice signal is converted into voice data by the voice signal / voice data conversion unit. Then, the scoring function unit compares the sound data with the performance data, and changes the display color of the location where the discrepancy between the musical piece in the lyrics, the lack of volume, the out of tempo, etc. occurs based on the comparison result. It is like that.
