The 'Green Green Grass of Home' singer, a coach on the upcoming BBC talent show, revealed that he was "blown away" by the auditions on the BBC talent show.
The Welsh legend said he will "definitely" find the winning act, saying: "I have got the natural voices on my team. What would I say to the other coaches? Bring it on!"
The 71-year-old went on: "I was blown away by the standard of the singers. We have all said that it's a shame we can only pick ten artists to be in our team. I would have loved it if I could have picked 20!"
Describing his mentoring style, the star added: "I'd like to think I am a fair coach. I am always listening to see if they are in tune.
"People are always coming to me to ask for advice, and it's nice to be able to give people tips. I know how much I really appreciated people giving me advice when I was younger."
With will.i.am, Jessie J and The Script's Danny O'Donoghue also on the panel, The Voice premieres on Saturday (March 24) on BBC One, hosted by Holly Willoughby and Reggie Yates.
