I'm a long-time fan of Ultrastar Deluxe, which is an open-source clone of Singstar. This is a karaoke game where people compete by singing along to the tune. It recognizes the notes you are singing and compares them to a vocals-timings mapping file for that particular song. The better you sing to the tune (getting the words correct doesn't matter), the higher your score.

While there are extensive libraries of fan-made song mappings, it's never enough, and there are very few mapped songs in languages other than English or Spanish (if you or your friends prefer your native language). Doing the entire mapping manually is time-consuming, not to mention that I am almost tone-deaf myself, which would make it even more difficult. I have been wondering for a long time what software I could use to make this process easier to automate. This seems like a great tool for capturing vocal timings and notes from original songs.

I have it on my bucket list to create a Singstar playlist in my native language and host a singing party with friends.

Does anyone have suggestions for other similar tools?
