One of the problems with searching for music is that in order to search for it, you need to know what it's called – and a lot of times you haven't the faintest idea what it's called, so you don't know what to search for. That's why Shazam was invented, so you could get your phone to recognise what music you were hearing, and it's why Soundhound took the idea further by enabling you to hum or sing a tune and look it up online. Now it seems YouTube is getting in on the act with its own hum-powered search feature in the YouTube app.
Shazam is owned by Apple these days, so it's very unlikely that it'll come to non-Apple services – so Google has apparently built its own voice-powered equivalent. In a support page unearthed by The Verge, Google details the search experiments it's making available to some users. And one of those experiments is sing-to-search.
