However, an additional function that has been determined to be used once may be continuously used while the karaoke system is being used. In the karaoke system of the present embodiment, since a plurality of users log in and use, the additional functions used for each user may be associated with each other, or the determined additional functions may be applied to all users. Whether or not to continue to use the additional function may be selected by the user from the above.

  In the above-described embodiment, as described with reference to FIG. 6, the first measured sound range measured last time is compared with the second measured sound range measured this time, but the first measured sound range that is the past measured sound range is used. May be calculated by taking an average of a plurality of sound ranges measured so far. In the present invention, in order to confirm the tone of the user's voice, not only the pitch range but also the pitch limit values such as the highest pitch value and the lowest pitch value may be used.

  In the above-described embodiment, the voice range and the pitch of the voice are used as the voice feature information for confirming the tone of the user's voice, but the voice feature information is replaced with the voice pitch instead of the voice pitch. S (volume) may be used. When using both the upper limit value and the lower limit value in the form that uses the loudness of the voice, the first measured volume width obtained in the last singing and the newly obtained first time 2 The amount of change is detected by comparing the measured sound volume ranges, and if the amount of change is increasing, it is determined that the user's singing ability is favorable. On the other hand, when the amount of change is reduced, it is determined that the user's singing ability is poor. Or it is good also as judging the tone of a user's singing ability using either an upper limit or a lower limit as a volume limit. Alternatively, in the case of volume, the determination may be made with an index related to voice volume instead of the upper limit value and the lower limit value. For example, in the voice volume acquisition process instead of the sound range acquisition process of the above-described embodiment, the user sings a specific phrase, and the average value of the volume of the sung singing voice is measured as voice volume information serving as an index of the user's singing ability. . When the voice volume information measured this time exceeds the voice volume information measured in the past, it is determined that the user's singing ability is good. On the other hand, when the voice volume information measured this time is lower than the voice volume information measured in the past, it is determined that the user's singing ability is not good. As described above, as the audio feature information, one or both of a value related to pitch and a value related to volume may be used. As for the value relating to the pitch and the value relating to the volume, at least one of the upper limit value and the lower limit value can be used. In addition, regarding the value relating to the sound volume, it may be possible to use an average value of sumo speech that is an index of the voice volume of the user.
