The result is output to the microcomputer 2. The above constitutes the karaoke apparatus.

Next, the operation of this embodiment will be described.
First, the user of the karaoke apparatus 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 on the CRTs 8 and 9 is selected, respectively. The lyrics display mode is
There are three modes: "All display mode" for displaying all lyrics, "Partial display mode" for partially displaying lyrics, and "No display mode" for not displaying lyrics at all. CRTs 8 and 9 can be set independently. It is.

In this case, among the settings for the CRTs 8 and 9 in the above three modes, combinations that are considered to be used relatively frequently are prepared in advance as shown in FIG. 2 and displayed on the CRTs 8 and 9. The user may be allowed to make a selection. Here, it is assumed that the partial display mode is selected for the CRT 8 and the full display mode is selected for the CRT 9.

When the partial display mode is selected, the microcomputer 2 selects an erasing rate which is a rate at which a part of the lyrics displayed on the CRT 8 or 9 is not displayed. If the non-display mode is selected for the CRT 8 or 9, no lyrics data is displayed on the selected CRT.

When the music number and the display mode are input as described above, the microcomputer 2 reads out the musical sound and the lyrics data corresponding to the music number from the hard disk 3 and outputs the musical sound data to the MIDI tone generator 4.

FIG. 3 shows an example of the format of the lyrics data stored in the hard disk 3. 1 on CRT 8 and 9 depending on the progress of the karaoke song
The lyrics to be displayed on a screen-by-screen basis, that is, the lyrics to be displayed are 12
It is 24 characters (including blanks) of 2 characters x 2 columns. When the partial display mode is selected and the erasure rate is input as 40% as described above, about 10 characters, that is, 40% of the 24 characters, are masked (erased) and are not displayed.

The microcomputer 2 calculates the number of characters to be masked from the input erasing rate as described above, and calculates the result of the calculation based on a predetermined erasing program among the 24 characters (for example, the number of characters to be erased is added to the head address of the data). "1" is added, and the number of erased characters is sequentially incremented and added to the added address (for example, "*" is assigned to the selected 10 characters and displayed in a masked state. However, when a blank is assigned to the mask, the blank is displayed as it is. By performing the above processing for all the lyrics data, a partial display pattern is created.

FIGS. 4A and 4B show CRTs 8 and 9 respectively.
3 shows an example of the screen display state. FIG.
Indicates a display state of the CRT 8 when the partial display mode is selected, and is displayed in a so-called “insect-eating” state in which lyrics are sometimes masked with “*”. FIG. 8B shows a display state of the CRT 9 when the all display mode is selected, in which all lyrics are displayed.

On the other hand, the music signal of the karaoke tune provided to the audio mixer 6 is amplified according to the set volume level and provided to the speaker 7, thereby being reproduced as a karaoke tune. The singer listens to the karaoke song and inputs a voice to the microphone 11 while singing the song while watching the worm-eating lyrics displayed on the CRT 8. The sound input to the microphone 11 is converted into an electric signal, and is amplified according to the volume level set in the audio mixer 6.
It is output from the speaker 7 together with the karaoke song.

In this case, the singer must sing while watching the worm-eating lyrics displayed on the CRT 8, so that the singer cannot sing correctly unless he / she remembers the lyrics of the song correctly. When the non-display mode is selected for the CRT 8, the lyrics are not displayed at all, making it more difficult to sing correctly. And the listener is CRT
Since the singer can listen to the singer's song while looking at the normal lyrics display of No. 9, if the singer sang the lyrics incorrectly, it can be immediately understood.

The voice input to the microphone 11 is A
/ D conversion is 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.

The pitch recognition determining section 12a recognizes the pitch of the voice input to the microphone 11, and the pitch is determined by the microcomputer 2.
At predetermined intervals (for example, 0.1 second), it is determined to what degree the pitch matches the correct melody to be sung to the given karaoke song (for example, the pitch of a guide melody included in the karaoke song). To evaluate the pitch matching degree. For example, the number of deduction points is set in accordance with the number of cents deviated from the correct pitch, and the points are sequentially subtracted from a predetermined point (for example, 100 points). Finally, the higher the score remaining (at the end of the karaoke song), the higher the pitch agreement.

The timing determining unit 12b synchronizes the utterance timing of the voice input to the microphone 11 with, for example, the guide melody at the above-mentioned predetermined interval, and compares the utterance timing with the utterance timing set in accordance with an appropriate phrase of the lyrics. It is determined whether they match or not as a timing matching degree.
For example, the deduction point is set according to ± m seconds from the correct utterance timing, and the deduction points are sequentially subtracted from predetermined points. The higher the final score, the higher the timing coincidence.

The voice recognition determining unit 12c recognizes the text of the voice input to the microphone 11 and determines to what extent the text matches the text of the lyrics of the karaoke song given from the microcomputer 2 to the predetermined level. The word matching is evaluated at the utterance timing of the word synchronized with the interval. For example, if the lyric word is "I" while the singer sings "I", the deduction point 1 is subtracted sequentially from a predetermined score. The higher the score finally left, the higher the degree of word matching.

At the end of the karaoke song, the scores of the singers' overall singing ability are scored, for example, by arithmetically averaging the scores of the respective coincidences output by the three determination units 12a, 12b and 12c. You. Therefore, the singing ability of the singer is scored, taking into account the element “how accurately the lyrics of the song are memorized” which has not existed in the past. The scored points are output to the microcomputer 2 and displayed on the screens of the CRTs 8 and 9, respectively.

As described above, according to this embodiment, the CRT 8
In the CRTs 8 and 9, the full display mode for displaying the lyrics data of the karaoke tunes to be displayed respectively, the partial display mode for displaying the lyrics in a worm-eating state, and the non-display mode for not displaying the lyrics at all are independent of each other. The microcomputer 2 displays the lyrics on the CRTs 8 and 9 in accordance with the selected display mode.
Singing along with the karaoke song while watching the lyrics display on RT8, the listener listened to the singer's singing while watching the lyrics display on CRT9.

Therefore, when the partial display mode is selected for the CRT 8, the singer must sing while watching the worm-eating lyric display of the CRT 8, and sings correctly if he does not remember the lyrics of the karaoke song correctly. Although it is difficult, the lyrics are partially displayed, so that it is possible to sing by guessing a part where the lyrics are not known. In addition, when the non-display mode is selected, it is necessary to sing in a state where no lyrics are displayed, so that it is more difficult to sing the lyrics correctly. And the listener
If you select the full display mode for CRT 9, you can listen to the singer's song while watching the normal lyrics display,
You can know whether the singer is singing the lyrics correctly.

Thus, the listener can enjoy the karaoke song with the new interest of how accurately the singer can sing the lyrics of the karaoke song, and the singer can also enjoy the karaoke song. By adding a game-like element of how to sing a song, entertainment can be generally improved.

According to the present embodiment, the scoring device 12
The pitch recognition unit 12a, the timing determination unit 12b, and the voice recognition determination unit 12c compare the singer's voice input to the microphone 11 with respect to the melody in which the singer's singing is sung along with the karaoke song. Judgment was made by judging whether the utterance timings match and to what extent the words matched the lyrics sung along with the karaoke song.
