Google Sound Search has now turned to be way better and all the credit goes to AI based song recognition. Sound Search feature can be used within the Google Assistant in order to find which song is being played in near vicinity.
Google had announced the 'Now playing' always-on music recognition feature for the Pixel 2 series of smartphones last year. It has the ability to recognise which song is currently being played. Google has also claimed that it has applied the same technology and made the Sound Search feature better.
'Now playing' also has the ability to sort songs through a database of about tens of thousands of songs and also uses neural networks to develop fingerprint which help to identify each song.
