Google has endowed its search engine with a fun new feature with the self-explanatory name “hum to search”: now whenever a song starts playing in your head, whose name you can’t remember, you can try humming its melody directly in the search. And Google will tell you the name, if of course it recognizes this most annoying melody by a set of sounds like “yes yes yes yes yes na na na naa naa ooo yeh”. The functionality, which is kind of a human version of Shazam, was one of the main announcements of the Search On presentation about the company’s latest advancements in AI.
“They all had such that a melody would get stuck in their heads, but we don’t remember its lyrics. Now, at times like this, you just have to hum to search, and our AI models can pick up the melody and find the song you want. “

Google says it has trained a neural network using machine learning algorithms so that it can identify possible song matches from a set of sounds. Companies emphasize that you don’t need to have a perfect musical ear to use the feature. At the appropriate request, or, more correctly, a voice melody, the system will display the most likely options.
As is customary in such cases, the researchers “fed” a large amount of data into the AI system during training.
Google explains how the technology works like this:
“The melody of a song is like a fingerprint: each has its own unique identity. We have created machine learning models that can associate humming, whistling or singing with the corresponding fingerprint. “
Capable of recognizing songs from a variety of sources, including people singing, whistling, or humming melodies and studio recordings, Google’s machine learning models convert the sound into a number sequence that matches the melody of the song. The algorithms also remove all other details such as backing instruments, timbre, and pitch of voice, leaving the main fingerprint of the song. The system runs these impressions through a database of thousands of songs from around the world, identifying possible matches in real time.
It is based on the development of the AI research team on music recognition technology. In 2017, the Now Playing program debuted on Pixel 2 smartphones, which uses deep neural networks for music recognition. A year later, the technology came to SoundSearch on Google’s app, while the company expanded its reach to a catalog of millions of songs. The hum search function is a further evolutionary development of technology with the ability to recognize a hum motif.
The functionality is now available in the Google mobile app for Android and iOS. You can access it both in the application itself (you only need to install the latest version), and through the Google Search widget. To activate the feature, you need to tap on the microphone icon and say the head command “What is this song?” or press the “Search for a song” button, and then hum a tune for 10-15 seconds.
On iOS, only English is currently supported, and on Android, the feature is available in more than 20 languages, including Ukrainian. In the future, the list of supported languages will be expanded. At least Google “hopes” so.
