Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a karaoke apparatus that is used so that a singer sings along with a performance output from a speaker.

[Prior Art] Conventionally, in a karaoke apparatus, the singing content when a karaoke user sings along with a karaoke performance has been evaluated using a scoring system, for example, with a score of 65 out of 100. The evaluation method is to judge the extent to which the pitch and tempo of the singing differ from the pitch and tempo of the karaoke performance, and how many times the pitch and tempo of the singing differ from the pitch and tempo of the karaoke performance, and to store the results in a storage means. When the karaoke performance was completed, the summer performance result was divided into scores and displayed as a score. [Problem to be solved by the invention] However, the singing evaluation was displayed only as a score as the final result. Therefore, as a karaoke user, it is important to have detailed and specific information such as at what point in time the pitch was uttered, or which phrase in the song was the tempo incorrectly set. There was a problem that the evaluation could not be known.

[Object of the Invention] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to make it possible to more specifically notify the evaluation of singing content.

[Means for Solving the Problems] In order to achieve this object, the karaoke device of the present invention has the following features:
As illustrated in FIG. 1, there is a performance data storage means M1 that stores performance data Do of a large number of songs and musical score data DI of the main melody in association with each other, and performance data DO selected from a large number of songs. A performance means M6 for performing a performance, a singing voice data input means M2 for inputting a singing voice by the user in accordance with the performance of the performance means M6, and a singing voice data input means M2 for inputting a singing voice from the singing voice data input means M2 in synchronization with the performance of the performance data DO. A sampling means M7 for sampling the singing voice data D2, a singing voice data storage means M4 for storing the singing voice data D2 sampled by the sampling means M7, and performance data Do by the performance means M6.
control means M that generates evaluation data D3 in which musical score data DI of the corresponding main melody read out from the performance data storage means M1 and singing voice data D2 read out from the singing voice data storage means M4 are superimposed on a staff score after the performance of
3, and evaluation data output means for printing or displaying this evaluation data D3.

[Function] The karaoke apparatus of the present invention having the above-mentioned configuration stores the singing voice data D2 sampled in timing with the performance data DO in the singing voice data storage means M4 during the performance, and after the performance is finished, the singing voice data D2 is stored in the singing voice data storage means M4. Since the evaluation data D3 is displayed or printed by superimposing the audio data D2 and the main melody score data DI on a staff score, it is possible to detect differences in pitch and tempo when comparing the main melody sung by a singer and the karaoke performance. The degree of time and pitch deviation will be concretely expressed on the musical staff.

By comparing and contrasting (b) and (b), singers can find detailed and specific information such as at what point in the vocalization the pitch was off, or in which phrase of the song the tempo was incorrect. You can know the evaluation.

In the comparison of (a direct, bI), i=1°2.4,
In section 5.7, the singing follows the main melody and matches the tempo, but the pitches are different, and the extent of the pitch deviation can be seen. It can be seen that in the part where i=3, the tempo and pitch were the same.

In the part i=6, the main melody note a is displayed or printed, whereas the singing note is not displayed or printed. This means that note ON and note OFF in performance data Do This means that the tempo of the song was not sung in time with note A6, which means that the tempo of the song was off from the main melody.

In the above embodiment, the karaoke user selects display or printing on the switch panel 5 after the performance ends, but the selection may be made before the performance starts. In this case, after the performance ends, the display or printing will be automatically performed without waiting for the karaoke user's operation.

Furthermore, the display and printing may be performed at the same time.

Furthermore, as a means for outputting the evaluation data D3, only the CRT monitor 8 or only the printer 10 may be used.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, the singer's singing voice data sampled in time with the performance and the musical score data of the main melody can be superimposed and displayed on a staff score. Since the structure is configured so that the pitch or tempo of the singer's singing content has shifted compared to the main melody, the singer can visually see at what point the pitch or tempo has shifted, or by how much the pitch has shifted compared to the main melody. You can learn more about it in detail.
