Google introduces song matching based on hums and whistles

Google has added a new search feature that allows users to find the name of a song by humming or whistling a few lines of the song. The feature was announced on Thursday via Google's official blog.

The feature is going to be part of Google's mobile app and Google Assistant. Users can start searching for a song by saying, "Hey Google, What's this song? " and then singing, humming or whistling a part of it for about 15 seconds.

Google's machine learning converts the audios sent by a user into number-based sequences that represent a song's melody. The search results will show a list of matching songs.

Google says that the machine learning models can match the users' hums, whistles or voice to create a unique identity, Google calls these identities "fingerprints".

The new feature will be available on Android in over 20 languages and on iOS in English.

"People ask Google, 'What song is playing?' almost 100 million times a month," Aparna Chennapragada, vice president and general manager for consumer shopping at Google, said during an unveiling of new search features on Thursday.

Google, on Thursday, also announced the new uses of Google Lens–Google's image recognition technology. Users can now tap and hold on an image in Google Chrome or the Google app, and the search engine will automatically show similar results, this feature is believed to be implemented by next month.
