Cohen announced yesterday that the BBC had acquired the rights to air The Voice next year, after reaching an agreement with creator John de Mol.
He told The Mirror that the show will avoid clashing with The X Factor next year, adding that he views the formats as two completely different shows.
He explained: "The Voice is a really stand-out format and it has got a lot of warmth and heart.
"It has got something in it for all ages with very high quality musicians involved. There is a real freshness to the fact you are picking people not on what they look like, just on how they sing.
"In terms of judges, we want a real range of musical styles, that is something they have done well in the States. I wouldn't like to compare the show to The X Factor, it is just a big new show for the BBC. And we will work hard to avoid our show clashing with The X Factor on ITV."
Cohen added that the BBC purchased The Voice in order to keep with the BBC's vision to entertain, as well as to educate.
"We have got Strictly Come Dancing as well, we want to provide really good Saturday night entertainment right through the year. The vision of the BBC is it is there to inform, educate and entertain and we take inform and educate very seriously, but we also take the entertain bit seriously.
"The BBC has a fantastic heritage of wonderful family entertainment on Saturday evenings.
"We buy in formats for shows very rarely, like The Apprentice, and we only do it when we think it is something really special and we can add something to it as the BBC, to make it even more special. So, every so often we will take something from abroad because we think it is worth it."
He revealed that he was glad to have fought off competition from ITV to buy the format.
"We were a little worried when ITV put in a bid but we fought really passionately for the show and worked hard to show how we felt, and hopefully that played a part when bigger bids came in."
Cheryl Cole is reportedly in negotiations for a judging role for The Voice.
