How to identify a song by humming on Android and iPhone

Forgotten song lyrics are no longer essential for finding a track. Google’s app can identify a melody after users hum or whistle it for 10 to 15 seconds on an Android phone or iPhone.

To use the feature, open the Google app, tap the microphone icon, and select “Search a song.” The system then processes the recording and offers possible matches within seconds. Users do not need perfect pitch or the exact lyrics, because the algorithm analyzes the sequence of notes.

Google’s “Hum to Search” feature uses machine learning to turn the captured audio into a numerical sequence representing the melody. The process removes instruments and vocal nuances, allowing the system to compare the underlying musical structure with thousands of recordings from around the world.

Virtual assistants can also respond to commands such as “What song is this?” Other mobile tools, including Shazam and SoundHound, identify songs through a touch button using ambient audio or voice. These services can recognize music playing through speakers or inside other applications, including when headphones are connected.
