I have seen some youtube videos of a speaker system that prints the lyrics whilst a song is playing.
If this could be incorporated so that when a track is played, the lyrics are output to the video portion, you then have instant karaoke, just with the lyrics playing
So here’s the clever bit, could the software listen to the song, create the lyrics, but suppress the vocals via neural mix.
Karaoke DJ’s would not need to buy special version of tracks.
As I doubted the existence of a speaker with a built in printer, I Googled your phrase. Are you referring to the Cotodama speakers that cost £2000 each?
The lyrics are shown on a screen, not printed. The unit connects to a database to find the correct lyrics, but it’s limited (2 million tracks, compared to 100 million on typical streaming services).
The software (DJay) couldn’t “create the lyrics” by “listening” to the song, as the lyrics need to appear on screen ahead of time. It would require a huge database of lyrics.
VirtualDJ finds lyrics by searching online which can then be associated with the track, and yes the vocals could be muted via stem separation, but it’s a manual process.
