The duo's 'Saturday Night Takeaway' is set to go head-to-head with the BBC talent show but the lads believe their show has the edge.
"But 'The Voice' for me lacks that sense of humour. I think it always has done."
Ant and Dec - who are also on course to top the charts with 'Let's Get Ready To Rhumble' on Sunday thanks to a nostalgic performance on last week's 'Takeaway' - said they are also feeling pretty confident about a rating victory.
"A lot of people have criticised 'The Voice' because of the way it tailed off at the end last time," said Ant. "But I think you'd be foolish to think it'll start like that.
"Those early rounds got very good ratings. I'm unsure what will happen, but we've put in some good graft and worked hard - you can't worry about it."
Despite 'Saturday Night Takeaway' finishing its run next month, Ant and Dec will still be competing with 'The Voice' when 'Britain's Got Talent' returns in the coming weeks.
'BGT' boss Simon Cowell is heating up the competition by encouraging viewers to tune into 'Takeaway' instead of 'The Voice'.
Saturday's show sees him team up with the Geordie duo to prank former 'BGT' judge Piers Morgan.
