New Google function - hum or whistle into a phone to find a song

Google Search announced on Thursday that users can hum or whistle a song to their mobile devices, and Google Search will find its name and artist as well as relevant search results like music videos. The search might result in several different songs, with the percentage of probability of each song. It works like this: A user can tap the mic icon in Google’s search app or the Google search widget and either tap the “search a song” button or tap the mic button and say, “What’s this song?”. If using Google Assistant, they can say, “Hey, Google, what’s this song?” Then, the user just sings, hums, or whistles the tune for 10 to 15 seconds - and voilà.
