The Voice UK Kids will air in Saturday night prime time in the spring of 2017.
The spin-off version to the main show will start just after the first ever series of The Voice UK On ITV, which is expected to begin in January.
The Daily Mirror newspaper reports that The Voice Kids will air on the weekends and see Will.i.am joined by two other judges.
The Black Eyed Peas star was previously confirmed to be returning to the panel, both for the main show and Kids spin-off.
will.i.am said: “I’m delighted to be continuing The Voice UK on ITV and being a voice of direction and guidance for the usual suspects, and I’m thrilled to add The Voice Kids to the mix.
"I know The Voice switched to ITV, but I’m not going to BREXIT The Voice UK. I’m happy to make ITV my home now. I love the UK.”
While the other judges aren't yet known, ITV have confirmed Emma Willis will be hosting.
Emma said previously: “Hosting The Voice Kids will be like being at my house on a Saturday night; lots of kids singing, with me trying to keep some kind of order.
"Thankfully, the musical genius that is will.i.am is there to bring some expertise to the table. It’s going to be pretty awesome.”
The Voice UK Kids will see singers aged 7 to 14 competing in a smaller version of the main singing competition.
