JP-2026074602-A - Karaoke equipment

Abstract

[Challenge] To suppress the decrease in scoring caused by overlapping guide melodies and vocal tracks. [Solution] The karaoke device (10) is provided with an acquisition unit (21) that acquires the singing pitch of the user who sings with a guide melody during performance, a calculation unit (22) that calculates the pitch difference between the reference pitch of the reference data and the user's singing pitch for each note, an identification unit (23) that identifies notes whose pitch difference between the reference pitch and the singing pitch is within a predetermined range as target notes, a generation unit (24) that generates shift data that pitch-shifts the reference pitch of each target note in the reverse direction based on the pitch difference, a storage unit (25) that stores the shift data in association with the user ID and the song ID of the karaoke song after the karaoke song has been played, and a performance unit (26) that pitch-shifts the reference pitch of the reference data and outputs a guide melody when the karaoke song is played.

Claims (2)

1. A karaoke device capable of outputting a guide melody based on reference data of karaoke songs, An acquisition unit that acquires the singing pitch of a user who sings along to a karaoke song with a guide melody playing, A calculation unit that calculates the pitch difference between the reference data's standard pitch and the user's singing pitch for each note, A selection unit identifies notes whose pitch difference between the reference pitch and the singing pitch is within a predetermined range as target notes, A generation unit that generates shift data to pitch-shift the reference pitch of each target note in the reverse direction based on the pitch difference, A storage unit that stores shift data after a karaoke song is played, associating it with the user's user ID and the song ID of the karaoke song. A karaoke device characterized by comprising: a performance unit that, when playing a karaoke song, refers to shift data corresponding to the user ID and song ID, and pitch-shifts the reference pitch of the reference data to output a guide melody.
2. The karaoke device according to claim 1, characterized in that the specified unit identifies target notes within a predetermined range that is below the lower limit for a passing grade during singing scoring, and is greater than or equal to a specified pitch difference lower than the said lower limit.

Description

This invention relates to a karaoke device. Conventionally, karaoke machines equipped with a function to score singing ability are known (see, for example, Patent Document 1). In the karaoke machine described in Patent Document 1, the singing voice and reference data are compared during karaoke performance, and the pass/fail status is determined for each note, resulting in a score for the singing voice. Furthermore, a karaoke machine that allows the user to switch the guide melody on and off according to their operation has also been proposed (see, for example, Patent Document 2). In the karaoke machine described in Patent Document 2, turning on the guide melody supports singing by beginners, while turning off the guide melody allows advanced singers to sing without being restricted by the guide melody. Japanese Patent Publication No. 2005-107328Japanese Patent Application Publication No. 07-028462 This is a diagram showing the configuration of the karaoke system according to this embodiment.This is a functional block diagram of the karaoke device according to this embodiment.This figure shows an example of the process for identifying the target notebook in this embodiment.This is a flowchart showing an example of the processing operation of the karaoke device according to this embodiment.This is a flowchart showing an example of the processing operation of the karaoke device according to this embodiment. The karaoke device of this embodiment will be described with reference to Figures 1 to 3. Figure 1 is a configuration diagram of the karaoke system of this embodiment. Figure 2 is a functional block diagram of the karaoke device of this embodiment. Figure 3 is a diagram showing an example of the target note specific processing of this embodiment. Note that, for the sake of explanation, the functional block diagram in Figure 2 shows functional blocks for realizing a specific processing, but it is assumed that the karaoke device has the configurations that it normally possesses. As shown in Figure 1, the karaoke system 1 comprises a server device 2 installed in a data center or similar location, and a karaoke machine 10 installed in a karaoke establishment or similar location. The server device 2 and the karaoke machine 10 are connected via a network 5 for communication. The server device 2 manages various information related to songs and various information related to users. A paired remote control device 11 is connected to the karaoke machine 10. When a user logs into the karaoke machine 10 by operating the remote control device 11, various user information is applied to the karaoke machine 10 by the server device 2. In this case, when the user ID and password are entered on the login screen of the remote control device 11, the user ID and password are transmitted from the remote control device 11 to the server device 2 via the karaoke device 10. The server device 2 identifies the user information using the user database, and the user information is returned from the server device 2 to the karaoke device 10, allowing the user to log in to the karaoke device 10. The karaoke device 10 stores the user information of the logged-in user. This user information includes singing history, including scoring values for each song, and shift data for each song, as described later. In addition to the remote control device 11, the karaoke machine 10 is also connected to a monitor 12, a speaker 13, and a microphone 14. The monitor 12 displays lyrics and other information along with background video based on video signals from the karaoke machine 10, synchronized with the karaoke performance. The microphone 14 converts the user's singing voice into a singing voice signal and inputs it to the karaoke machine 10. The speaker 13 emits the user's singing voice along with the performance sound signal from the karaoke machine 10 and the singing voice signal from the microphone 14. The remote control device 11 accepts various operations for the karaoke machine 10, such as song reservation. When the karaoke machine 10 starts playing a karaoke song, lyrics and background images are displayed on the monitor 12 in sync with the music. The karaoke machine 10 mixes the music signal and the vocal signal input from the microphone 14 using a mixer. This mixed signal is amplified by an amplifier and emitted from the speaker 13. In this way, when the user sings along with the karaoke music, the vocals are emitted from the speaker 13 along with the music. Furthermore, the karaoke machine 10 scores the user's singing ability, and the score is displayed on the monitor 12. The karaoke machine 10 also outputs a guide melody to support the user's singing. When singing while listening to the guide melody, the user may sing lower than the correct pitch, resulting in a lower score. This is because, when singing at the correct pitch according to the guide melody, the user's own singing voice overlaps with the guide melody, and they unconsciously try
