Speaking to Attitude magazine, Reggie said the new BBC One series would be "more credible" and wouldn't focus on sob stories.
Reggie, who fronts the show alongside Holly Willoughby, said: "On another show, where someone's father has nearly died and they've held the note, they're good to go.
"But that's not what 'The Voice' is about. Ours is far more credible than any other music competition show that I have seen.
"It's about musical talent, not about how they're dressed or how good they look."
The Voice, which sees Jessie J, will.i.am, Sir Tom Jones and Danny O'Donoghue on its panel of coaches, does however feature sob stories heavily in the auditions.
"Reggie might need to look at his notes again," a source tells the Daily Star. "In episode one there's a girl who has lost all her hair through alopecia and she has lost her confidence in performing. She hopes The Voice can restore that for her."
The Voice UK starts on BBC One on March 24.
