On Thursday, Google announced a new one feature called "hum to search", Allows users to locate songs by simply mumbling a part of a track.
Google says you do not need to worry about your music performance, and you do not need to be a singer to use this feature.
The new search feature is available in the Google app and on mobile devices, as well as in the Google Search widget. When using the widget, you must first tap the small microphone icon and search for the function by clicking the button labeled "search a song" or by saying "what is this song?" (what's this song?) Next, you will have to “sing” a part of the song.
The hum to search function is also available through Google Assistant. To identify a song, first ask “Hey Google, what is this song?” (Hey Google, what's this song?) before singing the song. According to company you should sing for 10 to 15 seconds.
The feature uses machine learning to identify possible tracks based on a person's audio sequence. After you sing a melody, Google will give you a number of "possible choices based on the melody".
A song can have thousands of recognizable features, and Google likens the melody of a song to a "fingerprint." So Google uses its machine learning to match your murmur, whistle or song to the right "fingerprint" of a melody.
The models are trained to identify specific songs from many sources, including studio recordings, songs, whistles and hums, according to Google, and everything else data of a recording, such as instruments, the pitch and timbre of the voice are removed, leaving a “fingerprint-based track sequence.” These sequences are then compared to thousands of others to determine potential matches.
Currently, the feature is available on iOS in English only. In the Android, hum to search is available in more than 20 languages and the company hopes to extend these capabilities to more languages, according to the announcement.
