Description

  The present invention relates to a karaoke recording system for mixing karaoke accompaniment music and a microphone input voice by a user, creating recording data for each karaoke piece, and writing the recording data to a portable recording medium. Relates to a karaoke recording system suitable for group participants.

  Recently, at a karaoke store or the like, as an optional service, karaoke accompaniment music output from a karaoke performance device and microphone input voice singing along with the music are mixed and recorded, and a CD-R, DVD, or the like is appropriately recorded. There is a place that provides a karaoke recording service that can be written (recorded) on a portable recording medium. In order to perform such a service, a recording device for a portable recording medium is required. Specifically, a CD-R recorder, a DVD recorder, or the like is required, which is configured separately from the karaoke performance device. Recently, some recorders are incorporated in karaoke performance apparatuses. As a writing procedure, recording data is formed by mixing the karaoke accompaniment music and the sound signal of the microphone input sound, recording the data in a predetermined recording unit, and then recording the data using a CD-R recorder, for example. Is converted into a CD-DA standard PCM data format and written to a CD-R.

  Conventionally, various techniques have been conceived in connection with such a recording service. For example, Patent Document 1 discloses a karaoke recording apparatus that can freely select music to be recorded on an appropriate portable recording medium assigned to each album. In Patent Document 2, when only karaoke accompaniment music is recorded, the recorded CD-R can be reused as it is for karaoke purposes, so that it is illegal under the copyright law. In consideration of this, a karaoke recording apparatus that can prevent only accompaniment music from being illegally recorded is disclosed.

By the way, karaoke music usually has a performance section (non-singing section) that the singer does not sing, such as prelude, interlude, and follower, but conventionally, accompaniment music and microphone input sound are recorded through the performance of karaoke music, The voice input by the microphone is recorded even in the non-singing section. If you are singing, the microphone input voice that is input to the microphone will erase the surrounding noise, such as the accompanying chat, even if it is recorded. Don't be. However, since there is a problem that the microphone input sound recorded in the non-singing section becomes useless noise, Patent Document 3 has conceived a technique capable of recording by eliminating the noise input into the non-singing section.

  FIG. 1 is a block diagram of a karaoke recording system in an embodiment of the present invention. The karaoke recording system (1) of the present embodiment is mainly composed of a karaoke performance device. This karaoke performance device is used to perform central control means (10) for controlling the overall operation and karaoke accompaniment music. It is mainly composed of recording means such as a hard disk (HDD: 11) in which performance data (24) and video data (25) are recorded. The central control means (10) includes a hard disk (11), RAM (12), sound source (synthesizer: 6), mixer (effector: 7), vocal adapter (14), MPEG decoder (15), synthesis A circuit (16), a CD-R recorder (writing means: 2) and the like are connected.

  Here, each component will be described a little. First, when the ID code of the music is input by the remote control device (3), the central control means (10) detects this by the operation input processing means (22), and the sequencer (21 ). This sequencer (21) mainly comprises a music sequencer, a lyrics sequencer, and a character pattern creation means, and reads out performance data identified by the ID code of the music from the performance data (24) of the hard disk (11). Next, the sound source (6) forms an acoustic signal according to the performance data corresponding to the music ID input by the processing of the sequencer (21) executed by the central control means (10). The formed acoustic signal is input to the mixer (7). The mixer (7) is a microphone from the acoustic signal generated by the sound source (6) and the microphone (5) input via the A / D converter (13). Mix the input audio signal with an appropriate balance. The mixed digital audio signal is input to the sound system (SS: 8). This sound system (8) includes a D / A converter and a power amplifier, converts an input digital signal into an analog signal and amplifies it, and emits karaoke accompaniment music and microphone input sound from the speaker (9). .

  The video data (25) recorded on the hard disk (11) is encoded in the MPEG2 format, and is subjected to playback processing by background video playback means (not shown) executed by the central control means (10). Are input to the MPEG decoder (15). The MPEG decoder (15) converts the input MPEG data into an NTSC video signal and inputs it to the synthesis circuit (16). The synthesis circuit (16) displays lyrics telop and scoring on the background video signal. The synthesized video signal is displayed on a display device (display means: 4).

  Next, the sound input interface and recording control means will be described. Two sound input interfaces are set, and during the performance of a predetermined karaoke piece, the first sound input interface (19) acquires sound signals corresponding to the performance data, and the second sound input interface ( 20) obtains an acoustic signal of the microphone input voice. The recording control means (18) mixes these input acoustic signals, converts them to PCM data, and uses them as recording data, which is recorded in the recording data recording section (28) of the RAM (12). In this embodiment, the music ID code corresponding to each recording data is also recorded in the music ID code recording unit (27).

  At this time, the central control means (10), with respect to the recording control means (18), based on the singing section data and the non-singing section data set corresponding to each karaoke piece, Control is performed so that an acoustic signal is acquired from the second acoustic input interface, and the acoustic signal is acquired only from the first acoustic input interface in the non-singing section. When the central control means (10) receives a voice instruction from the second sound input interface (20) in the non-singing section to the voiceprint matching means (17) and the recording control means (18), the central control means (10) In the predetermined area of (12), the voiceprint data recording unit (26) records the voiceprint data of the user with the characteristics of the voiceprint data of the voice instruction analyzed by the voiceprint matching means (17), and records the recorded data in correspondence with this. The recording data is recorded in the section (28). At the same time, the display device (4) is controlled to display the recorded data by adding the classification information when necessary.

  The voiceprint matching technique according to the present invention may be a conventionally known voiceprint matching means. The voiceprint matching means (17) of the present embodiment extracts voiceprint data from the microphone input voice and compares and matches the characteristics of a plurality of voiceprint data. It is. Specifically, for example, after noise components are removed from a voice signal input from a microphone and voice analysis is performed, voiceprint data is extracted and collated as kana information and formant information. The kana information is, for example, “ka”, “ki”, “ko”, “mi” when a kana character string word “kakikomi” is inputted by voice as a voice instruction for instructing writing. Each word of a character string indicating a character is voice-recognized and converted into code information. Formant information is a singular value related to the resonance frequency of the vocal tract and is information corresponding to each individual voiceprint, and is extracted as formant level, formant center frequency, formant bandwidth, and the like. Then, when a writing instruction for giving a voice instruction is issued, the user can be distinguished from the difference in the characteristics of the voiceprint data by such a method.

  FIG. 2 is a screen (D) showing an example of a list display of each recorded data using the display device as a display means. This screen (D) is automatically displayed at the timing when recording is completed in a predetermined procedure. It is displayed automatically or in a timely manner according to a user instruction. On this screen (D), serial number notation (30), song title notation (31), singer notation (32), CD-R burning (writing) instructor notation (33), etc. are posted. ing. Since these notations are sorted and displayed based on the category of the instructor notation (33), it is easy and clear at a glance who is in the desired writing category for each recording data. . Normally, the singer and the user who voiced the instruction are the same person, but the present invention is not limited to this, and when other users wish to record any singer's song. The user who voiced the singer does not necessarily have to be the same person. Further, in this embodiment, the singer and the indicator are indicated by symbols such as “A”, “B”, “C”, and “D” for each user, but the present invention is not limited to this. Instead, in a system that manages user IDs, the user's name and nickname may be written as they are instead of symbols.

  The central control means (10), with respect to the recording data for which the voice instruction has been received, for example, the user sees the list display of each of the divided recording data for the CR-R recorder (writing means: 2). After that, at the timing when the user has instructed to execute writing, the recording data is controlled to be written to a predetermined CD-R collectively for each section based on the instructor notation (33) section. More specifically, this writing control means that when recording data is recorded in the recording data recording section (28), write marking data is given to the data, and the recording data is written to the recording data as long as the marking data exists. This is control for operating the writing function of the CD-R recorder (2) after sending it to the face (23) or after sending it to the writing interface (23).

  In the present embodiment, each recording data is automatically written in a batch for each section. However, the present invention is not limited to this, and in the present invention, no one writes for each recording data. Since it can be easily and clearly understood at first glance whether the user is in the desired category, for example, the user may give another write instruction while viewing the list display of each recorded data.

  Hereinafter, based on the conceptual diagram of the mechanism of classification based on the recording control and the voice instruction shown in FIG. 3, the configurations of (K) and (K) described in claim 1 of the present invention will be described in more detail.

  First, as shown in (a), a singing section and a non-singing section are set based on singing section information (singing section data and non-singing section data) of a predetermined karaoke piece. In this embodiment, in order to set a singing section and a non-singing section, a method of detecting the presence / absence of display of lyrics telop and the color change time of lyrics characters in the karaoke apparatus is adopted. That is, a case where the lyrics telop is displayed is set as a singing section, and a case where the lyrics telop is not displayed is set as a non-singing section. Alternatively, the lyrics telop is displayed with an expression that changes the color of the lyric character string from left to right at the timing of starting singing after displaying the lyric character string in a row. May be a non-singing section.

  In addition, the setting of the singing section and the non-singing section in the present invention is not limited to these, for example, the display order of the lyrics character string in each karaoke song attached to the lyrics sequencer, its display / erase timing, and the displayed character string Lyrics rendering data describing the start / end timing of color change may be used. Furthermore, a method of using section data incidental to performance data is also conceivable. This section data is data in which data indicating each performance section is associated with the performance time series of the song, such as prelude, first singing section, interlude, second singing section, interlude,. It can be arbitrarily set in the MIDI data, and if this is acquired, the singing section and the non-singing section can be detected.

  During the performance of a predetermined karaoke piece, as shown in (b), the sound signal of karaoke accompaniment music is acquired for recording from the first sound input interface regardless of the singing section and the non-singing section. And as shown in (c), from the second acoustic input interface, in the singing section, the sound signal of the microphone input voice is acquired for recording, while as shown in (d), the non-singing section In, the voice instruction of the user is accepted without recording. This switching between recording and non-recording is performed by, for example, physically switching between a circuit for recording an acoustic signal as recording data and a circuit for analyzing a sound, or a software recording program for an acoustic signal. And processing by a voice analysis program. Then, as shown in (e), when a voice instruction is received from a microphone input voice in a non-singing section, as shown in (f), the recorded voice data is recorded according to the characteristics of the voiceprint data using the voiceprint matching means. Is divided.

  In the above embodiment, the karaoke performance device and the portable recording medium writing means (CD-R recorder) correspond to each other on a one-to-one basis, but the present invention is not limited to this. As shown in FIG. 4, it may be a centralized management type karaoke recording system. In this embodiment, a karaoke performance device (P) is installed in each guest room in the karaoke store, and these karaoke performance devices (P) have built-in recording control means. It is connected to a central management server (S) accompanying the R recorder (R). In each karaoke performance device (P), recorded data is formed and recorded in a recording file format in a predetermined recording section. When a dump request (recording data transfer command to the writing means) is performed on the recording data that has been instructed to be written by the user, the recording data is transferred to the central management server (S). The central management server (S) writes the recorded data with the CD-R recorder (R) while managing what kind of recorded data has been transferred from which karaoke performance device (P).

  In addition, the centralized management type karaoke recording system may include a plurality of CD-R recorders and a plurality of centralized management servers for controlling the respective CD-R recorders. A plurality of CD-R recorders may be connected to the central management server. Of course, the control function similar to that of the central management server may be incorporated in the CD-R recorder itself without using the central management server.

  As described above in detail, according to the karaoke recording system for group participants of the present invention, two sound input interfaces for acquiring sound signals are provided, and the user instructs writing in the non-singing section. When a voice instruction is received, it is classified according to the characteristics of the voiceprint data of the voice instruction, and each recording data is controlled to be managed for each division, so that it is suitable for group participants and each user likes. In addition to promptly specifying the recorded data, it is easy and clear to identify which user sang the recorded data, and the recorded data for each user can be efficiently divided and written to a portable recording medium.
