Problems solved by technology

But in the above-mentioned existing karaoke grading device, because there is only the shortcoming that can only be graded to a singer, the quality of other singers can only be compared with each other by each person's grading result
Therefore, it is impossible to carry out the game method of competing for singing at the same time.

no. 2 Embodiment

[0086] According to the second embodiment, a plurality of singers can simultaneously compete with their own singing masterpieces.

[0087] FIG. 7 shows the structure of the karaoke scoring device of the second embodiment.

[0088] In the karaoke scoring device 101 of this embodiment, the two singers use different microphones M1 and M2 respectively.

[0089] A / D converters AD1 and AD2 convert respective voices into voice signals.

[0090] The switch SW follows the selection signal S sent by the microcomputer 1b SW Select two sound signals.

[0091] Regarding other configurations, description thereof is omitted since they are the same as those of the first embodiment. However, the microcomputer 1b supplies the switch SW selection signal S SW In addition, it differs from the microcomputer 1a of the first embodiment in that it operates according to FIG. 8 .

[0092] The operation of this embodiment will be described below using the flowchart shown in FIG. 8 .

[0093] First,...

no. 3 example

[0108] The third embodiment is a further development of the second embodiment so that a plurality of singers can participate in the performance competition at the same time. When there is a singer's singing pitch within the detectable frequency band range and when there is a singer's singing pitch lower than this range, examples of detecting their voices are shown.

[0109] Fig. 9 shows the structure of the karaoke scoring device of the third embodiment.

[0110] As shown in FIG. 9, the karaoke scoring device 102 of the present embodiment is used simultaneously by a plurality of personnel n (n is a natural number) for singing competitions.

[0111] There are n microphones M1 to Mn, and n A / D converters are provided accordingly.

[0112] The switch SW1 follows the selection signal S from the microcomputer 1c SW1 Select one of n microphones. If the switch SW1 is provided not behind the A / D converter but before it, only one A / D converter corresponding to the microphones M1 to ...

Abstract

Apparatus for evaluating sound tone and karaoke scoring device, the devices are provided with an intonation detection means which detects the pitch of the sound of a first audio signal corresponding to a comparison audio, plural band pass filters each of which has a bandwidth that is made of dividing the frequency range corresponding to prescribed intervals in the frequency range having a prescribed bandwidth including the pitch of the sound of the first audio signals and respectively passes band signals in each bandwidth from a second audio signal corresponding to a reference audio, a level comparison means which respectively compares the amplitudes of the band signals that are passed through the filters and an evaluation means which conducts the evaluation related to the interval of the comparison audio against a reference audio based on the result of the means.

Description

technical field [0001] The present invention belongs to the technical field of so-called karaoke playback devices, in particular, to the technical field of karaoke scoring devices provided with a function of scoring a user's singing. Background technique [0002] In the karaoke reproducing device, there has been a karaoke scoring device that grades the quality of the user's singing. Existing karaoke scoring device has the function of detecting the guide music (quide vocal) only included in a certain channel from the stereophonic sound reproduced by the optical disc or the like recorded in the multi-channel sound mode used in karaoke. The function of scoring or evaluating the singing of the audience. Fig. 10 is an example of an existing karaoke scoring device. [0003] The karaoke sound reproduced by media such as laser discs is a stereophonic sound with left (Lch) and right (Rch) sound channels recorded in a multiplex sound mode. For example, Lch includes only the accompa...
