• Open the latest version of the Google app or find your Google Search widget. Tap the mic icon and say “what's this song?” or click the “Search a song” button. Start humming for 10-15 seconds.
• On Google Assistant, it’s just as simple. Say “Hey Google, what’s this song?” and then hum the tune of the song.
• Currently, this feature is available in English on iOS, and in more than 20 languages on Android phones. Google is hopeful of expanding the feature to more languages in the near future.

How does it work? Google said in a statement that a song’s melody is like its fingerprint. Each song has its own unique identity and hence, Google has built machine learning models that can match your hum, whistle, or sing to the right “fingerprint.” Whenever you hum a melody into Search, the machine learning models transform the audio into a number-based sequence representing the song’s melody. Google's models are trained to identify the songs on the basis of a variety of sources, including humans singing, whistling or humming, as well as studio recordings. -PTC News
