If you happen to’ve ever had the urge to converse with an AI model of your self, now you may — form of.
On Thursday, AI start-up Hume introduced the launch of a brand new “hyperrealistic voice cloning” feature for the newest iteration of its Empathic Voice Interface (EVI) mannequin, EVI 3, which was unveiled last month. The concept is that by importing a brief audio recording of your self talking — ideally between 30 and 90 seconds — the mannequin ought to be capable of rapidly churn out an AI-generated reproduction of your voice, which you’ll then work together with verbally, simply as you’ll with one other particular person standing in entrance of you.

I uploaded a recording of my voice to EVI 3 and spent a while idly chatting with the mannequin’s imitation of my voice. I hoped (maybe naively) to have an Uncanny Valley expertise — that exceedingly uncommon feeling of interacting with one thing that feels nearly utterly actual, but off-kilter sufficient to make one really feel barely uneasy — and was disillusioned when the EVI 3 me was extra like an audio cartoon model of myself.
Let me unpack {that a} bit.
Utilizing EVI 3’s voice cloning function
The imitation of my voice was, in some methods, undeniably reasonable. It appeared to pause intermittently when talking in roughly the identical approach that I are likely to do, with a contact of acquainted vocal fry. However the mirroring stopped there.
Hume claims in its weblog submit that EVI 3’s new voice cloning function can seize “features of the speaker’s character.” This can be a imprecise promise (most likely deliberately so), however in my very own trials, the mannequin appeared to fall brief on this regard. Removed from feeling like a convincing simulation of my very own conduct quirks and humorousness, the mannequin spoke with a chipper, eager-to-please tone that may’ve been well-suited to a radio advert for antidepressants. I like to consider myself as being pleasant and customarily upbeat, however the AI was clearly exaggerating these specific character traits.

Regardless of its usually puppy-like demeanor, the mannequin was surprisingly staunch in its refusal to strive talking in an accent, which appeared to me like it will be the form of playful voice train that it will excel at. After I requested it to provide an Australian accent a whirl, it mentioned “g’day” and “mate,” a few times in my regular voice, then instantly shied away from something extra daring. And it doesn’t matter what I prompted it to discuss, it tended to search out some inventive and roundabout method to circle again to the subject I used to be discussing once I recorded my voice as a pattern for it to make use of, paying homage to an experiment from Anthropic final 12 months by which Claude was tweaked to change into obsessed with the Golden Gate Bridge.
In my second trial, for instance, I had recorded myself talking about Led Zeppelin, which I would been listening to earlier that morning. After I then requested EVI 3’s voice clone of myself to elucidate its ideas on the character of darkish matter, it rapidly discovered a method to carry its response again to the topic of music, evaluating the mysteriously invisible pressure pervading the cosmos with the intangible melody that imbues a music with that means and energy.

In keeping with Hume’s website, person knowledge produced from interactions with the EVI API are collected and anonymized by default so as to practice the corporate’s fashions. You may flip this off, nevertheless, by way of the “Zero knowledge retention” function in your profile. For non-API merchandise, together with the demo linked above, the corporate says it “might” accumulate and use knowledge to enhance its fashions—however once more, you may toggle this off for those who create a private profile.
Whispering robots
AI voices have been round for fairly some time, however they’ve traditionally been relatively restricted of their realism; it is very apparent you are speaking to a robotic while you obtain responses from basic Siri or Alexa, for instance. In distinction, a brand new wave of AI voice fashions, EVI 3 amongst them, have been engineered not solely to talk in pure language but additionally, and extra importantly, to imitate the refined inflections, intonations, idiosyncrasies, and cadences that inflect actual, on a regular basis human speech.
“A giant a part of human communication is emphasizing the fitting phrases, pausing on the proper instances, utilizing the fitting tone of voice,” Hume CEO and chief scientist Alan Cowen informed me.
As Hume wrote in a blog post on Thursday, EVI 3 “is aware of what phrases to emphasise, what makes individuals snicker, and the way accents and different voice traits work together with vocabulary.” In keeping with the corporate, this marks a significant technical leap ahead from earlier speech-generating fashions, “which lack a significant understanding of language.”
Many AI consultants would take umbrage with the usage of phrases like “understanding” on this context since fashions like EVI 3 are skilled merely to detect and recreate patterns gleaned from their voluminous swathes of coaching knowledge, a course of that arguably does not depart any room for what we would acknowledge as true semantic comprehension.

EVI 3 was skilled “on trillions of tokens of textual content after which hundreds of thousands of hours of speech,” in response to Hume’s weblog submit. In keeping with Cowen, this strategy alone has enabled the mannequin to talk in voices which are rather more reasonable than would intuitively be anticipated. “With voice [models], what’s been most shocking is how human [they] might be simply by coaching on numerous knowledge,” he mentioned.
However philosophical arguments apart, the brand new wave of AI voice fashions is uncontroversially spectacular. When prompted, they will discover a a lot vaster vary of vocal expression than their predecessors. Firms like Hume and ElevenLabs declare that these new fashions could have sensible advantages for industries like leisure and advertising and marketing, however some consultants concern that they’re going to open new doorways for deception — as was illustrated simply final week when an unknown particular person used AI to imitate the voice of US Secretary of State Marco Rubio and subsequently deployed the voice clone in an try to dupe authorities officers.
“I do not see any purpose that we would wish a robotic whispering,” Emily M. Bender, a linguist and coauthor of The AI Con, just lately informed me. “Like, what’s that for? Besides possibly to disguise the truth that what you are listening to is artificial?”
Revolutionary turns into routine
Sure, EVI 3’s voice cloning function, like all AI instruments, has its shortcomings. However these are considerably overshadowed by its exceptional qualities.
For one factor, we must always keep in mind that the generative AI fashions hitting the market immediately are a part of the know-how’s infancy, they usually’ll solely proceed to enhance. In lower than three years, we have gone from the general public launch of ChatGPT to AI fashions that may roughly convincingly simulate actual human voices and instruments like Google’s Veo 3, which may produce reasonable video and synchronized audio. The breathtaking tempo of generative AI developments ought to give us pause, to say the least.

At present, EVI 3 can simulate a tough approximation of your voice. It is not unreasonable to anticipate, nevertheless, that its successor — or maybe grand-successor — will be capable of seize your voice in a approach that feels really convincing. In such a world, one can think about EVI or an analogous voice-generating mannequin being paired with an AI agent to, say, be part of Zoom conferences in your behalf. It may additionally, much less optimistically, be a rip-off artist’s dream come true.
Maybe essentially the most placing truth about my expertise interacting with EVI 3’s voice cloning function, although, is how mundane this know-how already feels.
Because the tempo of technological innovation accelerates, so too does our capability for instantaneously normalizing that which might have surprised earlier generations of people into awestruck silence. OpenAI’s Sam Altman made this very level in a current weblog submit: In keeping with Altman, we’re approaching the Singularity, but for essentially the most half, it looks like enterprise as normal.
