Simon Cowell said this year's X Factor contestants are not "big belters" but they will receive plenty of support.
When asked if this year's crop were as good as in previous years, he said: "I've got to put them in the studio yet.
"I'm happy with them but they're different. They're not like these big belting artists."
Cowell said he had not made his mind up yet about the winner's single.
