An update released by Google today (October 16) allows users to search for a song simply by singing, chirping or whistling the melody.
Announced at the Google Search event, and effective from now on, users can now find a song without knowing its title or even the lyrics.
Users can access the ‘Hum To Search’ feature by opening the ‘Google Search’ app or using the Google Search Widget. When you tap the microphone icon, you can ask “what is this song?” or click the ‘Find a song’ button.
In addition, if using Google Assistant, users may ask “Hey Google, what is this song?”.
From there, users will have a 10 – 15 second window to hum, whistle or sing the melody of a song they are thinking of, and Google will deliver a variety of matches, starting with the highest match percentage.
Watch an ad for the feature below:
“An easy way to explain this is that the melody of a song is like the finger of a finger: They each have a unique identity,” a post on The Google Blog says.
“We’ve built machine learning models that can match your hum, whistle or singing with the right ‘fingerprint’.”
“When you hum a Search melody, our machine learning models convert the audio into a number-based sequence representing the melody of the song, training the models to identify the songs based on various resources, including people singing, whistling or humming, as well as studio recording, ”the post continued.
“Algorithms also remove all other details, such as the accompanying instrument and timbre and tone of voice. All we have left is the song number sequence, or the fingerprint.”
This feature is currently available on both iOS and Android, with the latter providing the feature in more than 20 different languages.
