Description

[Detailed Description of the Invention] Technical Field The present invention relates to a recording and reproducing voice output device for emitting a song sung into a microphone from a speaker together with an accompanist using a recorded musical instrument or the like.

BACKGROUND TECHNOLOGY Recorded tape broadcasting involves listening to audio outputs such as songs from the playback output from recording tapes recorded on multiple tracks, and using musical instrument sound outputs as accompaniment, and then broadcasting the song sung through a microphone from a speaker. devices are commonly used. In this type of device, as shown in FIG. 1, audio sounds on a magnetic tape 1 on which audio sounds and instrumental sounds are recorded are outputted by a playback head 2, amplified by an equalization amplifier 3, Listened through earphones 4. On the other hand, the musical instrument sound is outputted from a reproduction head 5, passed through an equalizing amplifier 6, amplified by an output amplifier 7, and then emitted from a speaker 8. The singing voice output from the microphone 9 is amplified by a preamplifier 10, mixed into an output amplifier 7, and emitted from a speaker 8 along with musical instrument sounds.

Therefore, the voice of the person singing into the microphone 9 is composed of the musical instrument sounds reproduced on the recording tape 1 as accompaniment. However, in this type of conventional recording/playback voice output device, the microphone 9
The pitch of a person singing to a person who sings is different from the pitch of the recorded voice, and there is a drawback that the accompaniment of musical instruments cannot be played correctly. In other words, people who are not good at singing have the disadvantage that they are unable to match the pitch of the voice emitted from the speaker 8 with the recorded voice, and are unable to perform the correct ensemble to the accompaniment instrumental sounds. .

DISCLOSURE OF THE INVENTION The purpose of the present invention is to eliminate such drawbacks of the conventional methods, and to emit the output from a microphone of a person who is not good at singing into a normally recorded voice sound by changing the pitch, and adding white noise to make it sound like a normal singer. The purpose is to emit a voice that sounds like a synthesized voice.

The configuration of the present invention includes an analyzer section that includes a narrow band filter that inputs the audio output sung by a microphone and divides the entire band into a plurality of filters, and an analyzer that detects the output value and converts it into a voltage value.
A band filter that receives the recorded audio sound as input and has the same characteristics as the band filter in the analyzer section, and its output is controlled by the output voltage of the analyzer section.
A vocoder circuit is constituted by a modulating voltage control amplifier and a simulator section. These vocoder circuits are output for each of a plurality of bands, and these are mixed to form a vocoder device. The audio sound output from this vocoder device and the playback output of the recorded musical sound are mixed, and the mixed sound is emitted from a speaker via a power amplifier. The vocoder device is also a recording/playback voice emitting device comprising a microphone connected to the simulator section input of the vocoder device.

The effect of the present invention is that by inputting the microphone and the recorded voice to each terminal of a vocoder device having two input terminals, the recorded voice can be recorded depending on the intensity of each pitch of the voice sung by the microphone. You can change the intensity of each pitch of the voice sound. Furthermore, by switching and connecting a white noise generator to the input terminal of the recorded audio sound of the simulator section, it is possible to emit a pseudo sound close to synthesized speech. This white noise is
By substituting other various waveform generators and performing similar operations, varying pseudo-speech sounds can be obtained.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described with reference to the drawings.

In the embodiment of the present invention, as shown in FIG. 2, the musical instrument sounds on a recording tape 1 on which musical instrument sounds and voice sounds are recorded are transmitted from a playback head 5, through an equalization amplifier 6 and an output amplifier 7, and then emitted from a speaker 8. be done. On the other hand, the recorded audio sound passes from the playback head 2 to the equalization amplifier 3, and the output thereof is listened to through earphones 4, while being input to the simulator section 12 of the vocoder device 11. Here, the voice sung using the microphone 9 is generated by the analyzer section 13 of the vocoder device 11.
becomes the input. In this way, the signal is input to the vocoder device 11. The recorded audio sound and the audio sound from the microphone 9 are processed by a vocoder device 11, and the output of the recorded audio sound is coupled to the input of the output amplifier 7, where it is mixed with the musical instrument sound and output to the speaker 8. A voice is emitted from. i.e. microphone 9
The audio sound from the speaker 8 is emitted from the speaker 8 together with the recorded musical instrument sound with improved pitch.

Here, in the vocoder device 11, as shown in FIG. 3, the frequency band of the signal input to the analyzer section 13 is divided by a plurality of band filters 14 having a plurality of narrow bands. Changes in volume of the divided band outputs are detected by the analyzer 15 and output as voltage values.

On the other hand, the recorded audio signal input to the simulator section 12 is passed through a band filter 16 having the same characteristics as the band filter 14 of the analyzer section 13.
The output is input to a voltage controlled amplifier 17 which is controlled by voltage. Here, the voltage control amplifier 17 is connected to the analyzer 15 of the analyzer section 13.
The output is controlled by the voltage detected by the vocoder device 11. The vocoder circuits 19, 19', 19'' for each bandwidth each have two inputs and one input consisting of the input and output of the simulator section 12 and the input of the analyzer section 13. The voltage control amplifier 17 is controlled by the output voltage of the analyzer 15, but the input signal of the analyzer section 13 converts the sound determined by the height of the input to the simulator section 12 into the vocoder device 11.
The output is 18.

Now, when the singing is recorded as an audio sound with the instrumental sound of the recording tape 1 as accompaniment, input the recorded audio sound and the teacher's song to the simulator section 12,
When an amateur singer inputs a voice into the microphone 9 to the analyzer section 13, the singing of the analyzer section 13 becomes the pitch of the master of the simulator section 12. Vocoder circuit 1 divided into each of these bands
9, 19', 19''... When all bands are mixed, the amateur singer's song becomes the pitch of the master's song and is output from the vocoder device. Therefore, this output is combined with the recorded sound of the musical instrument. Output amplifier 7
By emitting sound from speaker 8 through
The accompaniment is recorded music, and the pitch of the singing from the microphone is equal to that of the recorded master's singing, and the pitch of the singing by an amateur singer is emitted from the speaker 8.

Further, if the output of the white noise generator 20 or other waveform generator is input to the simulator section 12 of the vocoder device 11 as shown in FIG. 4 instead of the audio sound from the recording tape 1, the vocoder device 1
As the output 18 from 1, it is possible to obtain a synthesized speech that is close to a pseudo-sound that would be generated synthetically.

As described above, according to the present invention, the strength of each pitch of the singing from the microphone 9 can be changed to the strength of each pitch of the teacher's recorded voice, so even those who are not good at singing can record. It has the advantage that the song can be played as a good accompaniment. It is also possible to listen to songs such as "Robot's Song" using synthesized speech.
