The Expanse is chock full of nifty gadgets, technology and, uh, sexual recreation. But just how realistic is all of it? Let's take a look at all of the future tech in each episode and discuss just how possible the 23rd century really is.
In Episode 2: "The Big Empty," Miller uses voice imitation tech to make him sound like Julie Mao, allowing him to access all of the voice-activated goodies in her apartment.
In a recent study done at the University of Alabama at Birmingham, researchers used an off-the-shelf voice-morphing tool, and developed a voice impersonation attack, in an attempt to penetrate automated and human verification systems. They concluded that advances in technology, specifically those that automate speech synthesis such as voice morphing, will allow people to build identical model's of a victim's voice from a limited number of samples.
Bottom line: this technology isn't far off.
