The Voice finalist Andrea Begley has said being partially-sighted might help her in tonight's show.
The singer, from Co Tyrone, has 10pc vision and has to memorise the lyrics to her song choices because she cannot read them off a monitor during the BBC show. But Andrea said she wants to be judged by her music, adding: "That's the way I expect the industry to take me, on the basis of what I do musically."
The singer even joked that her lack of vision helps in some ways.
She said: "It sounds awful, but I don't have to look at everybody and, sometimes, that can be a good thing if they don't look that happy to listen to me."
Andrea and the three remaining contestants, Matt Henry, Leah McFall and Mike Ward, go head-to-head in tonight's final.
Andrea's coach, The Script singer Danny O'Donoghue, said the show had learned from the failure of last year's winner Leanne Mitchell, whose debut single did not even reach the UK top 40.
He said they knew now that they had to develop a "game plan very early on" for the winning act.
He added that he wants to work with Andrea even if she does not win, and predicted that she will have an album out before Christmas.
Meanwhile, The Voice star Will.i.am said the latest series of the talent show will be "pointless" unless it produces a real star.
Will.i.am, who is coaching hot favourite McFall, said he wanted to produce an act to "get people dizzy".
He said: "These shows render themselves pointless if they can't identify something that's going to be on the radio and that's just me being part of the show. So we spend all this time looking for somebody and they aren't on the radio?
"After the show is finished, everyone should be scrambling, just like they were scrambling to find the next singer, just to make sure the person who won has a chance, has a shot, at the radio."
