FreddieMeter is another Google AI experiment you should try out. This tool asks the users to mimic Freddie Mercury’s voice and then rates the resemblance of their voice to Freddie's.
To see how well you can mimic Freddie, pick any of Freddie's available songs to sing. Then, the tool records and analyzes your voice. FreddieMeter shows a percentage of resemblance, based on melody, pitch, and timbre.
