Google’s latest feature will simply use your humming to search for the song you are looking for. It can also use whistling and singing.
So when next you have a song stuck in your head you can literally ask Google Assistant. You may not know the lyrics, but once you know the rhythm, it can find the song. You start by asking “what is this song?” Even if you can’t really whistle or sing. Some people may have tried this before with Shazam and was disappointed. Google has impressed us with the accuracy of this feature.
