It is a modem device used in the case of The host computer is adapted to transmit new karaoke song data at night time when the karaoke apparatus is not used, and the transmitted karaoke song data is written and stored in the hard disk 3 by the microcomputer 2. . As will be described later, this karaoke song data is composed of musical tone data and lyrics data.
[0018]
  The output port of the microcomputer 2 is connected to one input terminal of a MIDI (Musical Instrument Digital Interface) sound source 4 and a video mixer 5, and the output terminal of the MIDI sound source 4 is connected to a speaker 7 via an audio mixer 6. ing. The MIDI sound source 4 is composed of a synthesizer or the like, and reproduces musical tones of various musical instruments according to a given MIDI signal and outputs them to the audio mixer 6.
[0019]
  The output terminal of the video mixer 5 is connected to the two CRTs 8 and 9, respectively. A CRT (first lyrics display means) 8 is provided on the singer side for viewing by a karaoke singer, and a CRT (second lyrics display means) 9 is provided on the listener side for viewing by a listener other than the singer. Is provided. Both are arranged in a positional relationship in which the screens on the other side cannot be seen.
[0020]
  The output port of the microcomputer 2 is connected to the input terminal of the disc player 10. The output terminal of the disc player 10 is connected to the other input terminal of the video mixer 5. The disc player 10 has a built-in video disc such as a CD-ROM. The video disc contains video data to be output as a background video to the CRTs 8 and 9 when a karaoke song is being reproduced. Stored in a compressed state according to the MPEG standard.
[0021]
  The hard disk 3 contains karaoke music data (MIDI signal) given to the MIDI sound source 4 via the microcomputer 2 and the lyrics of the karaoke songs displayed on the CRTs 8 and 9 in a state synthesized with the background video by the video mixer 5. Image data (hereinafter referred to as lyrics data) is stored.
[0022]
  The output terminal of the microphone (audio input means) 11 is connected to the other input terminal of the audio mixer 6. The microphone 11 converts the input voice of the singer into an electrical signal and outputs the electrical signal, and the audio mixer 6 outputs the voice signal and the musical tone signal of the karaoke song played on the MIDI sound source 4 based on the set volume balance. They are mixed (mixed) and output to the speaker 7.
[0023]
  Further, the audio signal of the microphone 11 is given to the input terminal of the scoring device 12 which is a singing ability scoring means via the audio mixer 6, and the input / output terminal of the scoring device 12 is connected to the input / output port of the microcomputer 2. It is connected. The scoring device 12 includes a pitch recognition determination unit 12a, a timing determination unit (timing determination unit) 12b, and a voice recognition determination unit (voice recognition determination unit) 12c. Then, the data of the melody and timing data and lyrics data sung as a karaoke song given from the microcomputer 2 are compared with the A / D converted audio data input from the microphone 11, and the result Is output to the microcomputer 2. The above constitutes a karaoke apparatus.
[0024]
  Next, the operation of this embodiment will be described. The user of the karaoke device first operates various keys on the operation panel 1 or the remote controller 1a to input a number (song number) assigned to the song selected by the singer. At this time, the display mode of the lyrics to be displayed in the CRTs 8 and 9 is selected. There are three lyric display modes: “all display mode” for displaying all lyrics, “partial display mode” for displaying lyrics partially, and “no display mode” for not displaying lyrics at all. Each can be set independently.
[0025]
  In this case, among the settings for the CRTs 8 and 9 in the above three modes, a combination that seems to be relatively frequently used is prepared in advance as shown in FIG. 2, for example, and displayed on the CRTs 8 and 9 for use. You may make it let a person choose. Here, it is assumed that the partial display mode is selected for CRT8 and the full display mode is selected for CRT9.
[0026]
  In addition, when the partial display mode is selected, the microcomputer 2 selects an erasure rate that is a ratio of hiding a part of all the lyrics displayed on the CRT 8 or 9. When the non-display mode is selected for CRT 8 or 9, the lyrics data is not displayed on the selected CRT.
[0027]
  When the music number and the display mode are input as described above, the microcomputer 2 reads the musical sound and lyrics data corresponding to the musical number from the hard disk 3, outputs the musical sound data to the MIDI sound source 4, and the musical sound data. The lyrics data is output to the video mixer 5 in synchronization with the above. The MIDI sound source 4 outputs musical tones corresponding to the timbres of various musical instruments in accordance with the given MIDI signals, and gives the musical tone signals of karaoke songs to the audio mixer 6.
[0028]
  Further, the microcomputer 2 outputs a selection signal to the disc player 10 so that appropriate video data corresponding to the music number is output. Then, the disc player 10 reads the video data corresponding to the selection signal from the video disc, converts it into an NTSC signal, and outputs it to the video mixer 5. The video mixer 5 synthesizes the partial display and all display lyrics data given by the microcomputer 2 with the video signal output from the disc player 10 and outputs them to the CRTs 8 and 9. The CRTs 8 and 9 display the given video data on the screen.
[0029]
  Here, FIG. 3 shows an example of the format of the lyrics data stored in the hard disk 3. The lyrics to be displayed one screen at a time on the CRTs 8 and 9 according to the progress of the karaoke song, that is, the display target lyrics are 24 characters (including blanks) of 12 characters × 2 rows. When the partial display mode is selected as described above and the erasure rate is input as 40%, about 10 characters that are 40% of the 24 characters are masked (erased) to be hidden.
[0030]
  The microcomputer 2 calculates the number of characters to be masked from the input erasure rate as described above, and the result calculated based on a predetermined erasure program among the 24 characters (for example, the number of erase characters “1” at the start address of the data) The number of erased characters is sequentially incremented and added to the added address, etc.) “*” is assigned to the selected 10 characters and displayed. However, when a blank is assigned to a mask target, the blank is displayed as it is. The partial display pattern is created by performing the above processing for all the lyrics data.
[0031]
  4A and 4B show examples of screen display states of the CRTs 8 and 9. FIG. 5A shows the display state of the CRT 8 when the partial display mode is selected, and the lyrics are displayed in a so-called “worm-eaten” state masked with “*” in some places. FIG. 5B shows the display state of the CRT 9 when the all display mode is selected, and all the lyrics are displayed.
[0032]
  On the other hand, the musical tone signal of the karaoke song given to the audio mixer 6 is amplified according to the set volume level and given to the speaker 7 to be reproduced as a karaoke song. The singer listens to the karaoke song and inputs a voice to the microphone 11 while singing the song while watching the lyric display of the worm-eating state of the CRT 8. The sound input to the microphone 11 is converted into an electric signal, amplified according to the volume level set in the audio mixer 6, and output from the speaker 7 together with the karaoke song.
[0033]
  In this case, the singer must sing while watching the lyric display of the worm-eating state of the CRT 8, and therefore cannot sing correctly unless the lyric of the song is accurately remembered. In addition, when the non-display mode is selected for the CRT 8, the lyrics are not displayed at all and it becomes more difficult to sing correctly. The listener can listen to the singer's song while watching the normal lyrics display of the CRT 9, so that if the singer sings the wrong lyrics, the listener can immediately understand.
[0034]
  The voice input to the microphone 11 is A / D converted and input to the scoring device 12, and the pitch recognition determination unit 12a, the timing determination unit 12b, and the voice recognition determination unit 12c determine each element.
[0035]
  The pitch recognition determination unit 12a recognizes the pitch of the voice input to the microphone 11, and the pitch of the correct melody to be sung in accordance with the karaoke song given from the microcomputer 2 (for example, included in the karaoke song). The degree of coincidence of pitches is evaluated by determining the degree of coincidence with the pitch of a guide melody) at predetermined intervals (for example, 0.1 seconds). For example, a deduction point is set according to how many cents are deviated from the correct pitch, and is sequentially subtracted from a predetermined holding point (for example, 100 points). Finally, the higher the score remaining (at the end of the karaoke song), the higher the pitch coincidence.
[0036]
  The timing determination unit 12b matches the utterance timing of the voice input to the microphone 11 with the utterance timing set according to the appropriate phrase of the lyrics, for example, with respect to the guide melody in synchronization with the predetermined interval. Is determined as the degree of timing coincidence. For example, a deduction point is set according to how many milliseconds deviate from the correct utterance timing, and is sequentially subtracted from a predetermined holding point. The higher the final score, the higher the timing coincidence.
[0037]
  The voice recognition determination unit 12c recognizes the wording of the voice input to the microphone 11 and synchronizes with the predetermined interval how much the wording matches the wording of the lyrics of the karaoke song given from the microcomputer 2. The degree of word match is evaluated at the utterance timing. For example, when the singer sings “I” while the correct lyric wording is “I”, the score is deducted as 1, and the score is sequentially subtracted. The higher the score remaining finally, the higher the word match.
[0038]
  At the time when the karaoke song is finished, the score of the singer's overall singing ability is scored by, for example, arithmetically averaging the scores of the degrees of coincidence output from the three determination units 12a, 12b and 12c. Therefore, the singer's singing ability is scored in consideration of an element of “how accurately remembers the lyrics of a song” that did not exist conventionally. The scored points are output to the microcomputer 2 and displayed on the screens of the CRTs 8 and 9, respectively.
[0039]
  As described above, according to the present embodiment, the karaoke song lyrics data to be displayed on the CRTs 8 and 9 are all displayed in the normal display mode, the partial display mode is displayed in the worm-eaten state, and the lyrics are not displayed at all. The non-display mode can be selected independently for the CRTs 8 and 9, and the microcomputer 2 displays the lyrics on the CRTs 8 and 9 according to the selected display mode, and the singer sings the karaoke song while watching the lyrics display on the CRT 8. The listener listened to the singer's singing while viewing the lyrics display on the CRT9.
[0040]
  Therefore, when the partial display mode is selected for the CRT 8, the singer must sing while watching the lyric display of the worm-eating state of the CRT 8, and it is difficult to sing correctly unless the lyrics of the karaoke song are accurately remembered. However, it is also possible to sing by analogy with an unknown part of the lyrics by partially displaying the lyrics. Also, when the non-display mode is selected, it is more difficult to sing the lyrics correctly because it is necessary to sing without any lyrics displayed. Then, if the listener selects the all display mode for the CRT 9, the listener can hear the singer's song while viewing the normal lyric display, so that the singer can know whether or not the singer is accurately singing the lyrics.
[0041]
  Therefore, the listener can enjoy the karaoke song with the new interest of how accurately the singer can sing the lyrics of the karaoke song. By adding the game-like element of singing in the same way, it is possible to improve the entertainment as a whole.
[0042]
  According to the present embodiment, the scoring device 12 converts the singer's voice input to the microphone 11 into a karaoke song in the pitch recognition determination unit 12a, the timing determination unit 12b, and the voice recognition determination unit 12c. It was graded by judging how much the pitch and utterance timing matched with the melody sung together, and how much the words matched with the lyrics sung along with the karaoke song.
[0043]
  Therefore, how accurately the singer can sing the lyrics of a karaoke song by scoring in consideration of the accuracy of the lyrics, which has not existed as a scoring element of singing ability in the past, You can further enhance your interest and enjoy more karaoke songs.
[0044]
  Furthermore, according to the present embodiment, the microcomputer 2 has a setting function capable of setting an erasure rate that is a ratio of hiding a part of the lyrics in the partial display mode, and when the erasure rate is set, Since the partial display pattern corresponding to the erasure rate is created by calculation, an extra storage capacity for storing the partial display pattern in the hard disk 3 in advance is not required, and a predetermined partial display pattern is read. Since the non-display portion can be changed each time as compared with the case of putting out, the partial display pattern can be diversified.
