Youka is a free site that creates a version of a karaoke song for any YouTube video, according tomedia The Verge. Youka is an acronym for YouTube Karaoke, which separates vocals from tracks and extracts lyrics from online sites. Andy Baio, the technology expert who first discovered the application, noted that the service is most likely to use Spleeter, an open source AI tool that separates vocals from songs.
As long as there are lyrics on the line, the app can run on any song. Youka offers several different language options, so it also applies to some non-English songs. Vocal separation works in two ways, so you can listen to an unsung karaoke version of a song (accompaniment only) or just an accompaniment-free version of a human voice.
Vocal separation is not perfect – people can still hear very faint K.K. Slider-like sounds in the background. If people want to watch videos without a side for some reason, they can even use them on regular videos such as vlogs.
Youka’s creators say the site currently costs $2,000 to host and running it is an expensive operation. The creators said they planned to open source “before the lawsuit.”
