There has been mounting speculation in recent weeks on whether Jessie J will quit the singing contest, which also features will.i.am, Sir Tom Jones and The Script's Danny O'Donoghue on the panel.
Quizzed by the Radio Times on whether he wants to reinstate the same coaches next year, he said: "I hope so. God, yeah. I'd love all our judges to come back. I love them in multiple ways."
Cohen challenged the view that the judges are too friendly, insisting: "It's one of the great aspects of the show, that tonal quality, which we are very keen to maintain.
"I think the emphasis on constructive criticism is one of the fresh and exciting things about it."
Meanwhile, responding to Simon Cowell's claims that The Voice is similar to X Factor and other talent shows, Cohen hit back: "They made their decision about who they believed in with their backs turned.
"The key thing is that the selection of the teams by the judges is blind."
The 38-year-old boss also suggested that he will not use NBC's revamp as a precedent to shake up the reality show's format in the UK.
"We'll look at the end of the series but I think we're in a good place and I don't imagine mega-changes," he added.
Reports earlier this month indicated that producers would make immediate changes to the BBC programme because of falling viewing figures.
Ratings for The Voice have tailed off from a peak of 10.7m in April to under 6m in the last fortnight.
