The MMA fighter, who stars in Steven Soderbergh's upcoming movie, became the subject of scrutiny earlier this week when sources connected with the film claimed that her voice had been changed in post-production.
Carano confirmed the reports in a recent podcast for MMA blog No Holds Barred.
"Steven Soderbergh wanted [Carano's character] Mallory Kane to be a completely different entity than Gina Carano," she said. "So he definitely went in and I went in to AVR and he did some tweaking."
She insisted: "Even though it might not sound exactly like me, there are still parts of me that are in there."
The 29-year-old went on to say that she does not care her voice was altered.
"I'm just honoured to be a part of it," Carano said. "There was a little joke that I was saying that even if [Soderbergh] would have shaved my head and put Bill Clinton as my voice, I would have still done it."
Carano's Haywire co-star Michael Fassbender recently revealed that the MMA fighter did not wear any padding for their fight scene.
Soderbergh previously stated that he built the film around Carano because she "can break people in half".
Haywire will be released on January 20, 2012.
