Despite what Americans and voters see on television, the Ivanka Trump in real life is a little different than the person who is splashed across screens.

Trump, the president’s eldest daughter, has a voice that’s an “octave” deeper when in private; vacillates between “defiant” and “lighthearted”; and curses like her father, Donald Trump, and her husband and fellow senior White House adviser, Jared Kushner, according to the Washington Post.

The description might stand in stark contrast to the one of the woman who has made countless television appearances defending her father and touting his agenda.

If you’ve caught her old interviews on TV, or watched The Apprentice episodes she guest-stars in, you’ve undoubtedly noticed that Ivanka used to speak very differently. Whether it’s a product of coaching or a personal choice (and experts say it’s likely both), there’s been a marked change in her voice’s tone, pace, and even her vocabulary.

Noel Casler, who worked with the Trump’s on The Apprentice, says Ivanka’s voice is just for show:

Ivanka’s voice is totally phony, she curses like a sailor and has a deeper timbre when not ‘on camera. The ‘Baby Doll’ voice is something that was devised for Donald’s pleasure, all the sibilant ‘s’ are completely put on. They are all playing a part in Faustian bargain, or GOT.

Back in 2003, 21-year-old Ivanka starred in a documentary called Born Rich, which was all about what it’s like to be young and extremely wealthy. In it, her voice sounds flatter and scratchier than it does today.

In her 2007 appearance on Late Night with Conan O’Brien, Ivanka sounded more relaxed and at ease with being interviewed.

Nine years later, Ivanka addressed the 2016 Republican National Convention, introducing her father. She sounds much more polished now.

In this recent interview with Fox Business Network, Ivanka responds to Samantha Bee calling her a “feckless c—” on her show Full Frontal.

Now she has that whispery baby voice.
