Google on Thursday announced a handful of updates to its Search function, touting that it has implemented artificial intelligence (AI) and machine learning to improve the user experience.
Users can now hum, whistle, or sing a melody to Google via the mobile app by tapping the mic icon and saying, "What's this song?" or by clicking the "Search a song" button.
Humming for 10-15 seconds will give Google's machine learning algorithm the chance to match the song.
The feature is currently available in English on iOS, and in around 20 languages on Android, with more languages coming to both platforms in the future, Google said.
The search giant's AI updates also span spelling and general search queries.
This includes a new spelling algorithm that uses a deep neural net, which Google claims has significantly improved its ability to decipher misspellings.
In a blog post[1], Google said it wanted to focus on spelling updates as one in 10 queries are misspelled.
"In fact, this single change makes a greater improvement to spelling than all of our improvements over the last five years," the blog says.
"A new spelling algorithm helps us understand the context of misspelled words, so we can help you find the right results, all in under 3 milliseconds."
Similarly, Search will now index individual passages from pages to allow the specific location of a searched block of text to be located.
Neural nets have also been applied to understand subtopics around an interest, which Google said would help deliver a greater diversity of content when users make broad searches.
"As an example, if you search for 'home exercise equipment', we can now understand relevant subtopics, such as budget equipment, premium picks, or small space ideas, and show a wider range of
