BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, a case where an audio device for reproducing a singing of the present invention is applied to a karaoke apparatus will be described. In FIG. 2, audio equipment for reproducing a singing is roughly classified into a karaoke reproducing unit 1, a separation circuit 4, an audio conversion circuit 5, an external speaker 18, a microphone 19, and a laser death (L).
D) It comprises a changer 24 and a CRT 25 as a display device.

The karaoke reproducing section 1 is, for example, a communication karaoke apparatus, and includes a timing circuit 10, a communication control circuit (I / F) 11, a bus 12, a CPU 13, and a work RAM.
14, a MIDI sound source 15, a sound source mixer 17, a storage device 20 such as an HDD (hard disk drive), a character generation circuit (VDP) 22 for lyrics for image reproduction, and a video mixer 2
3. An input / output device (I / O) 26.

[0008] Karaoke playback unit 1 via communication control circuit 11
Is connected to the communication line 3 and can receive music data from the remote host 2 at a speed of, for example, 5 music per song as needed. The input / output device 26 receives a request signal from a remote controller (not shown), and if the requested music is in the storage device 20, the CPU 13 reads out music data, that is, MIDI data of karaoke data or the like from there.

The music data is composed of character data 6 of lyrics, timing data 7 of the number of beats thereof, and MIDI data 8 of musical instrument timbre and melody. The character data 6 of the lyrics is the lyrics of a song to be sung by an audio device, a singing reproduction device, a music device, or the like.

The MIDI data 8 is melody data including musical instrument types and timbres, and the melody data is composed of performance data (signals) 35 and melody line data 36 having continuous singing intervals. .
The melody line data 36 is for creating a melody of a lyric portion of a song to be sung by an audio device, a singing reproduction device, a music device, or the like.

The music data read out from the storage device 20 or received from the host 2 is decompressed in the work RAM 14 by the CPU 13 and the character data 6 is stored there.
, Timing data 7 and MIDI data 8 are stored. The character data 6, the timing data 7, and the MIDI data 8 are all separated and sent to the audio conversion circuit 5 by the separation circuit 4, and the individual MIDI data 8 is sent to the MIDI sound source 15.

On the other hand, the character data 6 is sent from the work RAM 14 to the character generation circuit (VDP) 22, and the timing data 7 is sent to the timing circuit 10, respectively. The timing data 7 is information for changing the color of the lyrics characters synchronized with the performance. The singer's voice signal from the microphone 19 is sent to the sound source mixer 17 and subjected to predetermined amplification and singing voice correction. The MIDI sound source 15 reproduces the accompaniment sound based on the designated instrument sound based on the instrument tone and the melody data 8, mixes the singing voice from the microphone 19 with the sound source mixer 17, and outputs the sound from the speaker 18.

In a character generation circuit (VDP) 22, a character pattern is generated from the character data 6 of the lyrics, and the lyrics characters are mixed with a background image from an LD changer 24 by a video mixer 23 and displayed on a CRT 25. The lyric character data 6 also includes a kanji code, and is not necessarily a single character single unit. In accordance with the timing data 7, the timing circuit 10 changes the coloring of each lyric character (including Chinese characters) displayed on the CRT 25 at the timing of singing.

Next, the configuration of the voice conversion circuit 5 will be described in detail with reference to FIG. The voice conversion circuit 5 includes a generated sound discrimination device 30, a voice source data table 31, a voice generation circuit 33, a timing addition circuit 37, a modulation processing circuit 39,
/ A converter 32.

In the generated sound discriminating device 30, since the kanji and kana are mixed in the character data 6 of the lyrics arranged in the order of singing, the kanji is converted to the phonetic kana of a single phonetic character to form a continuous kana sequence 41. I do. For example, single character data 41 of a kana string without a kanji is generated from a kanji kana string of “I am,...” To “Watashiha.

The basic speech source data table 31 stores data obtained by sampling and tabulating basic Japanese speech. The basic Japanese speech is a standard digital signal of an utterance source corresponding to 50 sounds, numbers, alphabets, and the like, and is a plurality of sound source data separated by a single sound.

The timbre which determines the characteristics of the standard digital signal has individual differences such that the male voice is different from the female "A" even if the voice is the same "A". Anyone can sample the voice, but for example, the best-selling singers have high singing fees, so the singing ability is high, but the singing is not sold and the cost is low. To create each standard sound digital signal.

The sound generating circuit 33 includes a generated sound discriminating device 31.
The corresponding standard digital signal is selected and determined from a large number of standard tone digital signals in the audio source data table 31, for each single tone character data 41 consisting of a sequence of kana arriving continuously from. That is, a basic sound generation process of applying a standard sound digital signal to the single sound character data 41 of the lyrics is performed, and a single sound sound signal 42 is continuously generated.

The timing adding circuit 37 determines the duration of each continuous single sound audio signal 42 in accordance with the timing data 7 and generates a timed audio signal 43. That is, for example, until the next voice signal 42 comes, the voice signal 42 currently being voiced is extended and continued so that voice output is performed in synchronization with the timing of the number of beats.

In accordance with the melody line data 36 of the MIDI data 8, the modulation processing circuit 39 modulates the single-tone sound signal 43 with time into a predetermined pitch, gives strength and weakness to melody modulation processing, and performs a singing digital signal which is continuous as a song. Create 44. The D / A converter 32 converts the singing digital signal 44 arriving at the time difference into an analog singing signal 45 and sends the analog singing signal 45 to the sound source mixer 17 of FIG.

In the sound source mixer 17, the analog signal of the singing voice and the performance signal from the MIDI sound source 15 are mixed.
Output to the speaker 18. The singing voice created by the voice converter 5 is automatically heard from the speaker 18 in accordance with the performance of the tune requested by the karaoke reproducing unit 1.

Since the voice is uttered by the standard sound digital signal of the person sampled in the voice source data table 31,
A singing voice is heard from the speaker 18 as if the person were singing. Even if you do not sing to the microphone 19, you can hear the singing voice along with the performance tune with the voice in the voice source data table 31, as if playing a recorder. This invention, for example, the singer "Tokoko Kato" of "Shiretoko Jijo" sings well, so you can sing in the karaoke karaoke, but the other songs "happy family" is unfamiliar, those who can not sing well, It is convenient when listening and practicing alone.

The singer "Tokiko Kato" can practice without a music CD-ROM of "Happy Family". In addition, a singing voice reproduced at an accurate pitch from the voice conversion circuit 5 is sung to the microphone 19 while secretly listening through the earphone. In this case, the analog singing signal 45 is attenuated by the volume 40. If the person who goes to the microphone 19 sings according to the singing voice of the earphone, the person can sing well and others can hear only the voice of the microphone 19, so that they can be cheered and cheered, and the excitement will be excited.

In order to output a vocal sound from a karaoke apparatus, a considerably large amount of data is required. If this method is used, the existing karaoke data can be processed without increasing the data amount, and the singing by the model singer can be performed. Can be realized. Almost no additional data is needed. In the case of the communication type karaoke apparatus, the singing voice of the model singer can be realized without increasing the usage of the communication line. By storing the voice of the operator himself / herself on the table, a song that matches the pitch can be realized and appreciated without practicing or singing in real time.
