The Sing Your Song app allows you to sing your own versions of your favorite songs, and find the most popular version of the song matching the lyric on Spotify.
The process is a three step process:
1. Speech recognition and interpretation
2. Search for songs containing the lyrics
3. Matching with the most popular song on youtube
The AI is under constant development, and if you donĀ“t get a successful lookup at your first try, give it another. Maybe you should try to pronounce the lyrics a bit clearer.
The application works best with english, but it might be able to interpret some other languages with a bit of luck.
