Adele has addressed claims by long time David Bowie producer Tony Visconti, that her voice had been altered to sound the way it does on her records.

Visconti recently signed on as a judge for UK reality television show Guitar Star, and made the claim during a promotional interview.

Speaking to the Daily Star, Visconti lamented the sound of modern music, calling what you hear on the radio "fluff", and saying what you're hearing is "90 per cent computerised voices".

"We know Adele has a great voice but it's even questionable if that is actually her voice or how much has been manipulated. We don't know," he said.

"There's a sound to pop now that is so perfect it's boring, because everything is fixed."

At a recent concert, Adele addressed Visconti's criticism in front of her fans, in true Adele style.

"Some d***head ... tried to say that my voice was not me on record. Dude, suck my d***," she said.
