Discovering new artists has always been important to me and the UK has no shortage of talent, so I can only imagine what this experience will be like for everyone involved. I can't wait to get going and start developing each individual’s own sound!"

Colour key:

There was a change to the blind auditions format for 2017; if all the coaches reject an auditionee they keep their back to the singer and will not say what they thought about their performance, as well as not being able to meet them. The blind auditions began filming on 19 October 2016 at dock10, MediaCityUK in Salford.

Each coach has the length of the artist's performance to decide if they want that artist on their team. Should two or more coaches want the same artist, then the artist will choose their coach.

The series premiere aired from 8.00pm until 9.35pm.
