BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. The present invention will be described below with reference to the drawings.
First, a singing practice device using the karaoke device 1 of the present invention will be described with reference to FIG. The karaoke device 1
Communication line 2, pitch measuring circuit 3, forward volume 5, reverse volume 6, and separate remote controller, separation circuit 12, MIDI sound source 10, tempo circuit 9, pitch reference circuit 8, display control circuit 11, pitch correction circuit 4, , Amplifier 13,
Mixer 14, separate speaker 18, separate microphone 19,
It comprises a CRT 7 as a separate display device.

The karaoke data received from the communication line 2 includes video data and music data.
These are separated in step 2. The video data is characters and background images of lyrics, the music data is MIDI data, and the video data is sent to 11 where the display timing is adjusted and CR
Display at T7. An existing television or the like is used for the separate speaker 18 and CRT 7, and the MIDI data is reproduced by the synthesizer of the MIDI sound source 10 into performance sound data of the musical instrument, tempo data, and pitch data. The pitch reference circuit 8 detects only the pitch signal of the main melody from the output of the MIDI sound source 10 and sends it to the pitch correction circuit 4 and the pitch measurement circuit 3.

The tempo circuit 9 detects only the tempo data from the output of the MIDI sound source 10 and sends it to the display control circuit 11. The display control circuit 11 controls the color change of the characters in the video data according to the tempo data. The singer sings into the microphone 19, and the singing voice signal is amplified by the amplifier 13 and sent to the mixer 14. The pitch correction circuit 4 includes a pitch reference circuit 8
The singing voice signal is constantly corrected according to the reference pitch from, and sent to the mixer 14 via the positive volume 5. The performance sound data and the corrected voice are mixed by the mixer 14 and a singing according to the performance is heard from the speaker 18.

The singer sings according to the tempo of the music piece while watching the color change of the lyric character displayed in 7. The pitch measuring circuit 3 includes a singer's voice from the amplifier 13 and a pitch reference circuit 8.
And compare it with the reference pitch from. The singer's interval and the reference interval and the degree of coincidence are quantified by the difference amount, for example, "0,
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 "is output. The difference" 0 "is almost the same as the singer's pitch and the reference pitch, and the difference" 1 "is The difference amount “2” is almost equal to the difference amount “3”, and the difference amount “10” is almost out of range.

The normal volume 5 and the reverse volume 6 are controlled by the same difference "0-10" from the pitch measuring circuit 3.
However, the normal volume 5 adjusts the volume “0-10” proportional to the difference “0-10”, and the reverse volume 6 adjusts the volume “0”.
The volume "10-0" is adjusted in inverse proportion to -10 ". A selection control circuit is composed of the pitch measuring circuit 3, the normal volume 5 and the reverse volume 6. That is, the difference amount is" 0, 1, 2, 3 ". ,
At 4, 5, 6, 7, 8, 9, 10 ", the reverse volume 6
Is "10, 9, 8, 7, 6, 5, 4, 3, 2,
1, 0 ", and the output of the primary volume 5 is"
The volume is adjusted to be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ″.

In a place where the singer is good at singing, the pitch measuring circuit 3 outputs the difference "0 or 1", the positive volume 5 becomes the volume "0 or 1", and the processed voice from the pitch correcting circuit 4 is audible. Disappears, but reverse volume 6 has volume "10"
Or 9 ”, and only the singing voice from the amplifier 13 (microphone 19) is heard. In places where the singer is not good at singing,
The pitch measuring circuit 3 outputs the difference “10 or 9”, the positive volume 5 becomes the volume “10 or 9”, and the pitch correcting circuit 4
You can only hear the processed audio from the
Becomes "0 or 1", and the singing voice from the amplifier 13 (microphone 19) cannot be heard. If the singing ability of the singer is acceptable, the singing voice and the processed voice can be mixed and heard. Only when the pitch is off, you can hear the corrected processed sound, so you can see exactly where it was wrong.

During singing, it becomes easy to see the difference between the part where the singer's utterance pitch is correctly pronounced and the part where the singer's utterance pitch is incorrectly pronounced. If you hear a lot of self-voice, you can score yourself that the pitch is solid. When the processed pitch is heard, the singer can change the pitch of the pronunciation and perform real-time voice training in an effort to hear a lot of self-voice.

During the singing, the difference between the part where the singer's pitch is uttered correctly and the part where the singer's pitch is uttered incorrectly can be clearly understood. If you can hear a lot of your own voice, you can score yourself that the pitch is sound. If you hear the processed voice, the singer can be cautious of the utterance and give an indication of the effort to change the pitch. Note that the karaoke apparatus 1 is not limited to communication karaoke, but may be one in which karaoke songs are stored in advance.
