It has an auxiliary storage unit 109 stored therein.
[0003]
In the operation of the karaoke apparatus according to the prior art, when a song is selected, a target song to be reproduced as karaoke is searched from the song data file 108 and data is supplied to the sequencer 101. The music data file 108 stores a sequence of musical scale and length data corresponding to musical notes for each musical instrument.
[0004]
Lyrics are given to the main melody which is the base of the music. Here, data indicating the main melody is also given.
[0005]
Further, the sequencer 101 reads out the music data file, extracts the sound source from the musical instrument sound source file 107 according to the musical instrument number added to the music data, adds the pitch and length data of the sound source, and performs audio processing. It is supplied to the unit 104.
[0006]
Further, the digital signal is converted into an audio signal by the audio processing unit 104 and supplied to the speaker 105. The voice of the user input to the microphone 106 is converted into an electric signal and supplied to the audio processing unit 104.
[0007]
Then, the lyrics data added to the main melody is read out by several lines by the lyrics display unit 102 and supplied to the display 103. At the same time, information on the playing position of the currently playing main melody is supplied from the sequencer 101, and the corresponding lyric data is obtained one bar or one note at a time. The corresponding lyrics data is supplied to the display 103 with the character color changed. As a result, the place where the current song should be sung is indicated to the user through the display 103.
[0008]
When reading out the lyrics in the karaoke system according to the above-described conventional technique, the karaoke is generally read out by displaying all the lyrics and reading the lyrics by voice synthesis. However, when this method is adopted, it is extremely difficult to sing according to the read lyrics. On the other hand, if the karaoke lyrics display portion is read aloud by speech synthesis, it is read aloud simultaneously with the progress of the song, which makes singing itself difficult.
[0009]
Therefore, in order to generate a lead narration that is a pre-reading voice of the lyrics and teach the lyrics by voice, a voice signal processing unit that generates a hamo voice of karaoke singing is used to reproduce the timing, reproduction speed, and reproduction frequency of the guide vocal data. A karaoke apparatus has been proposed in which this guide vocal data can be used as a lead narration which is a voice for pre-reading the lyrics of the next phrase in a non-singing section between phrases (see Patent Document 1). ).
