Description

  The present invention relates to a karaoke system that copes with a transmission delay of singing voice, and in particular, sings the same karaoke song at the same time using a plurality of karaoke performance devices installed in different places (for example, different karaoke shops). In response to the transmission delay of the singing partner's singing voice transmitted through the transmission path, the singer's singing voice's singing voice's singing voice's singing voice's The present invention relates to a karaoke performance device capable of eliminating a sense of incongruity.

  The currently popular karaoke performance apparatus has a function (for example, a remote duet function) for simultaneously singing the same karaoke music using a plurality of karaoke performance apparatuses installed in different places (for example, different karaoke shops). There is something to do. In such a karaoke performance device, the singing partner's singing voice is transmitted via a transmission line such as a telecommunication line, so that the singing party's singing voice arrives with a delay due to the influence of traffic or the like in the transmission line. Is assumed.

  Therefore, various techniques for solving such inconveniences in remote singing have been proposed (see, for example, Patent Document 1 and Patent Document 2). The technique described in Patent Document 1 relates to a karaoke system capable of confirming whether or not the communication state of a transmission path is suitable for a communication duet before the communication duet is performed. This karaoke system is a system capable of selecting a plurality of karaoke performance apparatuses connected to a host apparatus (server) via a transmission path and performing a communication duet. It is determined whether or not the karaoke performance device is being used by a certain use state determination unit, communication test execution unit, and communication state determination unit. Then, a communication test for the transmission line is performed between the non-use karaoke performance device determined to be unused and the host device, and the communication state of the transmission line is suitable for the communication duet based on the result of the communication test. Whether or not it is determined.

  Moreover, the technique described in Patent Document 2 relates to a remote duet system for performing a duet of music without worrying about the delay of the other party's voice. In this remote duet system, a part (A) where only a singer A (for example, a male) sings a music, a part (B) where only a singer B (for example, a female) sings, a singer A and a singer B together It categorizes into each part of the singing part (D) and the part (M) where no one sings. And in each karaoke performance apparatus, the reproduction | regeneration timing of a part (A) and a part (B) is adjusted according to the charge part of the music. Thereafter, if the part in charge is the part in charge of the singer A, the playback timing of the part (A) is accelerated by L (network delay time) / 2, and the playback timing of the part (B) is delayed by L / 2. If the part in charge is the part in charge of the singer B, the playback timing of the part (B) is accelerated by L / 2 and the playback timing of the part (A) is delayed by L / 2.

  However, the technique described in Patent Document 1 determines in advance a karaoke performance device suitable for a remote duet, and a user who uses each karaoke performance device has no karaoke performance device. If so, it is not notified in advance whether a remote duet can be performed. Therefore, when actually trying to perform a remote duet, it may not be possible to perform the remote duet because it is a combination of karaoke performance devices that are not suitable for the remote duet.

  In addition, the technique described in Patent Document 2 uses a plurality of karaoke performance devices installed in different places (for example, different karaoke shops) to sing each karaoke piece in advance when singing the same karaoke piece at the same time. It is necessary to divide and memorize the parts. For this reason, in recent years, karaoke systems that have recorded various versions of duet songs, such as live sound and personal video, can divide parts only for remote duets, and delay time for each part. It is impractical to adjust the reproduction timing of each karaoke performance device by judging the above. That is, such prior work requires a great deal of labor when creating music data of karaoke music, and there is also a problem that the load on the karaoke system due to adjustment of reproduction timing is large.

  The present invention has been proposed in view of the above-described circumstances, and is transmitted through a transmission line when simultaneously singing the same karaoke piece using a plurality of karaoke performance apparatuses installed in different places. Provided is a karaoke system capable of eliminating a sense of incongruity of a singer due to a difference between a sound emission timing of a karaoke performance sound and a sound emission timing of a singing partner's singing sound in response to a transmission delay of the singing partner's singing sound.

  The delay time measuring means is means for measuring the transmission delay time of the received singing voice with the karaoke performance device of the singing partner who performs the remote singing. The proxy reproduction sound generation means is means for generating proxy reproduction sound to be emitted from the speaker in accordance with the transmission delay time of the singing sound. The delayed singing voice supplementing means is generated by the proxy reproduction voice generating means from the start timing of the singing voice based on the reference data of the karaoke music until the transmission delay time measured by the delay time measuring means elapses. The proxy playback voice generated by the proxy playback voice generation means is output from the time when the transmission delay time measured by the delay time measuring means has elapsed until the end timing of the singing voice output based on the reference data. And means for outputting adjusted singing voice using the received singing voice.

  In the karaoke system corresponding to the transmission delay of the singing voice having the above-described configuration, the proxy reproduction voice can be a synthesized voice corresponding to the attribute information of the singing party, and the singing party is the same karaoke in the past. It is possible to use the singing voice of the singing partner stored when singing the music.

  According to the karaoke system corresponding to the transmission delay of the singing voice according to the present invention, the remote singing in which a plurality of users sing the same karaoke music at the same time using a plurality of karaoke performance devices installed in different places ( For example, when performing a remote duet), even if there is a delay in the singing voice of the singing partner due to the condition of the transmission path, until the measured transmission delay time elapses, the guide vocal or singing Singing voice or the like sung by the other party in the past can be output as proxy playback voice.

  Therefore, even in a remote duet, the user can use the same karaoke performance sound and karaoke performance sound and lyrics telop color as in the case of a normal singing (for example, duet) in which no delay occurs using the same karaoke performance device. Singing can be performed without a sense of incongruity according to the timing of replacement.

  In addition, by using the synthetic voice corresponding to the attribute information of the singing partner or the singing voice of the singing partner stored when the singing party sang the same karaoke song in the past as the proxy playback voice, there is no more discomfort. The proxy reproduction sound can be emitted.

For example, when performing a remote duet, the IP address of the karaoke performance device 10 used by the singing partner is acquired from the server 90 after the singing partner is determined. Then, the transmission delay time between the karaoke performance device 10 used by itself and the karaoke performance device 10 used by the singing partner is measured. Specifically, in a TCP / IP network, packets are transmitted / received using the echo function of the ping command, and the average response time is measured, whereby the transmission delay time between the karaoke performance apparatuses 10 used for remote duets is reduced. It can be measured. In this embodiment, as shown in FIG. 2, the transmission delay time with the karaoke performance device 10 of the singing partner is about 80 msec, and the singing voice of the singing partner is also delayed by about 80 msec. Will be transmitted.

  The timing for measuring the transmission delay time is set at an appropriate interval according to the status of the data communication line 80. For example, the transmission delay time is measured every time music selection reservation information is transmitted, or at every appropriate interval from the start of performance of karaoke music. Just go.

  The utterance timing of the original singing voice (sound emission timing from the speaker 40 when there is no delay) can be detected based on the reference data, and the timing includes lyrics such as “ki” illustrated in FIG. The start timing of the pronunciation of each syllable constituting the syllable, the timing at which the pitch is changed during the syllable pronunciation, and the like.

<Proxy playback audio generation means>
The proxy reproduction sound generation means 108 includes an electronic device and a program for generating proxy reproduction sound to be emitted from the speaker 40 in response to the transmission delay of the singing sound. In other words, in the proxy reproduction sound generation means 108, a transmission delay occurs in the singing partner's singing voice transmitted via the data communication line 80, and this delay time is, for example, from about 40 msec where the singer feels uncomfortable with the delay. Assuming a case where the proxy reproduction sound is about 120 msec which is an upper limit at which the substitute reproduction sound cannot be heard unnaturally, the proxy reproduction sound for supplementing the silent state in the delay time and generating the sound is generated.

  As the proxy playback voice, for example, a guide vocal prepared for karaoke music can be used. The guide vocal is an exemplary singing voice, and is an auxiliary singing voice that is output as an auxiliary to the karaoke singing when singing karaoke music that the singer is not good at or singing. In the present embodiment, the singing voice of the guide vocal is selected based on the reference data of the karaoke music, and the sound emission timing is determined.

  Moreover, the synthetic | combination audio | voice corresponding to the attribute information of the other party who performs karaoke singing can be used as substitute reproduction | regeneration audio | voice. That is, when the user of the singing partner logs in to the system, data such as gender distinction, age, etc., which is the attribute information of the user of the singing partner, can be acquired. After being received by the communication control means 105 of the performance device 10, based on the received attribute information, by generating a proxy playback voice that approximates the singing voice that the singing party actually sings, the singing voice of the singing party and the proxy When connected to the reproduced sound, it is possible to eliminate the uncomfortable feeling caused by the difference in sound quality.

  Moreover, the singing voice memorize | stored when the singing partner who performs a remote duet sings the same karaoke music in the past can be used as a substitute reproduction | regeneration audio | voice. That is, when the singing partner logs in to the system, when the singing voice stored when the singing party sang the same karaoke song in the past is stored in the server 90, the stored singing voice is used as the proxy playback voice. To do. In this case, since the proxy reproduction voice is the singing voice of the singer who is the singing partner, even if the proxy reproduction voice is emitted, there is no sense of incongruity.

  In addition, when the attribute information of the singing partner stored in the server 90 and the singing voice stored in the past are used as the proxy playback voice, the transmission delay time in downloading the attribute information data and the singing voice is considered, It is preferable to download these data in advance and store them in the karaoke performance device 10 using the timing when the singing partner performing the remote duet is confirmed or when the karaoke music piece performing the remote duet with the singing partner is confirmed. .

<Delayed singing voice supplement means>
The delayed singing voice supplementing means 109 outputs the proxy playback voice from the time when the singing voice is released based on the reference data of the karaoke music until the transmission delay time measured by the delay time measuring means 107 elapses. The proxy playback voice and the received singing voice generated by the proxy playback voice generation means 108 are output from the passage of the transmission delay time measured by the delay time measuring means 107 to the end timing of the singing voice based on the reference data. It consists of an electronic device and a program for outputting the adjusted singing voice used.

<Sound of substitute playback sound>
The sounding start timing of the original singing partner's singing voice (sounding start timing from the speaker 40 when there is no transmission delay) and the output end timing of the singing partner's singing voice (from the speaker 40 when there is no transmission delay) The sound emission end timing) can be determined based on the reference data of the karaoke music piece.

  As described above, the sound emission start timing of the original singing partner's singing voice (sounding start timing from the speaker 40 when there is no transmission delay) and the singing voice actually transmitted from the remote singing party There is a delay time between the sound emission timings. Therefore, if no measures are taken, the singer feels uncomfortable because there is a difference between the sound emission timing of the karaoke performance sound and the sound emission timing of his / her singing voice and the singing voice of the singing partner. Therefore, in the present invention, by generating proxy reproduction sound (for example, a guide vocal as shown in FIG. 2 (a)) corresponding to the transmission delay of the singing partner's singing sound, the uncomfortable feeling of the singer is eliminated. ing.

  That is, as shown in FIG. 2 (b), in the case of a singing voice (syllable) called “KI”, the sounding start timing of the original singing voice of the singing partner (the speaker in the case of no transmission delay) Since there is a discrepancy between the sound emission timing of the “KI” singing voice actually transmitted from the remote duet singing partner, no countermeasures are taken. Otherwise, there will be no sound during this period (about 80 msec in the example shown in FIG. 2). Therefore, as shown in FIG. 2 (c), in the transmission delay section in which the shift occurs, the proxy reproduction sound is output to cancel the silence state.

  Then, when the timing at which the singing voice actually transmitted from the remote duet singing partner is emitted from the speaker 40 is reached, the proxy reproduction voice and the singing voice of the singing partner singer are synthesized (crossfade). Then, the proxy playback voice is connected to the singer voice of the singer of the other party.

  Then, at the output end timing of the singing voice based on the reference data (the timing of the end of sound emission from the speaker 40 when there is no transmission delay), the amplitude of the singing party's singing voice is rapidly attenuated, and the singing party's singing without any sense of incongruity Terminates syllable sound in speech. Here, when the syllable is composed of consonant plus vowels (for example, “K” plus “I”) as in the singing voice of “KI”, the first syllable of the singing partner's singing voice is received. When the sound is released from the sound, “KI” of the singing partner's singing voice received after the “KI” of the proxy reproduction sound is emitted, and “KIKI” is emitted, so that it is unnaturally heard. Therefore, the syllable of the singing partner's singing voice following the proxy playback voice “KI” is made to be heard naturally by excluding the consonant and only vowels and releasing it as “KII”.

  Also in the karaoke performance apparatus 10 of the singing partner, the user who performs the remote singing is similar to the normal singing (for example, duet) in which the delay performed using the same karaoke performance apparatus 10 does not occur by performing the same processing. In addition, it is possible to sing with no sense of incongruity according to the singing voice of the singer, the karaoke performance sound, and the color change timing of the lyrics telop.

<Music playback control means>
The music reproduction control means 110 drives a sound source (synthesizer) based on the performance control data extracted from the music data corresponding to the music ID, generates a musical sound signal constituting a karaoke performance signal, and converts it into an analog signal for mixing. 60 is an electronic device for outputting to 60. Also, the mixing amplifier 60 sends out the singing voice signal input from the microphone 30, the singing voice signal of the singing partner subjected to the delay countermeasure processing input from the delayed singing voice supplementing means 109, and the music reproduction control means 110. This is a device for mixing the karaoke performance signal to be output and amplifying it by an amplifier function and outputting it from the speaker 40.

<Video playback control means>
The video reproduction control means 112 uses the background video data extracted from the background video database 104b and the lyric characters created based on the lyric rendering data included in the music data during the performance of the karaoke music, as the music of the karaoke music. The electronic device is used to synchronize with data and output a singing moving image or the like shot by the camera of the singing partner to the display device 50 during remote duet.
