Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing the appearance of an automatic karaoke copying system according to the present invention.
The CRT 3 displays images and lyrics corresponding to the selected karaoke. For example, if you select a famous singer's song another orion, the screen will show the background related to the selected song (Orion constellation and the distant view of the mountains) and "I will be strong for you ..."
Is displayed. The singing singer 2 looks at the lyric telop 4 displayed according to the performance of the karaoke by the wireless microphone 1 and sings well from the speaker even if he does not sing with a voice that resembles the singer in particular. Below the CRT 3, a communication karaoke commander 5, an amplifier 6, and a video generator 7 are arranged.

FIG. 2 is a block diagram showing an embodiment of the circuit of the automatic karaoke copying system for karaoke according to the present invention. The karaoke operation unit 18 includes an operation unit 8, a storage unit 9, an audio unit 10, and a video unit 11. A voice operation unit 12 is added to the karaoke operation unit 18. The voice calculation unit 12 decomposes a singer's voice received from the microphone 1 by the antenna 17 into a pitch and a tone data portion 14 and a singing singer's voice received from the microphone 1 by the antenna 17 into a pronunciation portion and a pitch portion (this portion is not used). It comprises a decomposing unit 13 and a voice operation circuit 15 for calculating and synthesizing the sounded part of the decomposed song singer, the pitch of the singer and the timbre data part 14.

The storage unit 9 stores a large number of karaoke songs, background images and lyrics telops corresponding to the songs, and also stores pitch and tone data of songs adapted to the karaoke performances of many singers. . The arithmetic unit 8 reads the pitch and timbre data of the singer selected before the start of the karaoke from the storage unit 9 and sends the singer's pitch and timbre data to the voice arithmetic unit 14. Simultaneously with the start of the karaoke, the performance data of the selected song, the background image and the lyrics telop corresponding to the selected song are read from the storage unit 9, and the performance data of the selected song is stored in the audio unit 1.
0 is reproduced as a performance sound and sent to the amplifying unit 6 and the speaker 16
Output from The selected background image and lyrics telop corresponding to the music are converted into a video signal in the video section 11 and displayed on the CRT 3.

FIG. 3 is a flow chart for explaining the operation of the karaoke automatic song imitation system according to the present invention. When a song of a singer to be sung is selected by the communication karaoke commander 5, a background image and lyrics telop are displayed on a screen, and a performance sound is output from a speaker. Microphone 1
When the singer's voice is input more, the voice portion is separated (step (hereinafter referred to as "S") 301). The pitch and timbre data of the singer of the selected song are acquired by the voice operation unit 12 (S302), and the voice portion, the pitch of the singer and the timbre data are synthesized (S303). The synthesis is performed for each unit subdivided by a predetermined time width, and the synthesis of the voice from the microphone, the pitch of the singer, and the timbre data is performed until the performance ends (S304).

FIG. 4 is a diagram for explaining an example of a singing operation according to the present invention, and shows a waveform example in which a pronunciation portion of a karaoke singing singer is superimposed on a characteristic portion of the singer. In addition,
The waveforms shown in FIG. 4 and FIG. 5 described later are sample waveforms exaggerated for easy understanding. For example, it is assumed that, for a sound source that pronounces a vowel “A”, the singer's formant frequency characteristic is the frequency characteristic (tone color portion) of (b) and the singer mimics the formant frequency characteristic of (c). For this sound source, the singer's formant frequency characteristics are used. If the singer mimics, for example, “ka”, the frequency characteristic of “ka” differs from the formant frequency characteristic of “a” by 20 as shown in FIG.
Is generated. Similarly, when the singing singer pronounces "sa", the frequency characteristic of "sa" produces a difference 21 from the formant frequency characteristic of "a" as shown in FIG. The differences 20, 21 are combined with the singer's formant frequency characteristics in (a), and the waveforms of the frequency characteristics shown in (e) and (f) are formed. The singer's formant frequency characteristics are also stored as data for vowels other than "A" and for fricative sounds and explosive sounds, and the same synthesis processing as described above is performed.

FIG. 5 is a diagram for explaining an example of singing operation according to the present invention, and shows examples of pitch and volume waveforms. It is assumed that a singer of a certain song has a frequency characteristic as shown in (a) and a corresponding part has a frequency characteristic as shown in FIG. It is assumed that the song singer of the same part has a frequency characteristic as shown in (c), and the corresponding part has a frequency characteristic as shown in (d) as the volume. The singer's singer part is used as it is, and the singer's singer part is not used. As for the sound volume (volume), the frequency characteristic of the singer of (b) and the frequency characteristic of the singer of the singing singer of (d) are combined to form a waveform of the frequency characteristic shown in (e). 4 (e), (f), FIG. 5 (a), and FIG. 5 (e) are synthesized, and a song is played from the speaker according to the performance.

[0012]

As described above, conventionally, in order to mimic a song, it has been necessary to imitate the voice color, the pitch, and the pronunciation with its own mouth with a special ability. For example, if the pronunciation is mimicked, there is an effect that anyone can easily imitate a singer by performing karaoke.
