Should you’ve ever had the urge to converse with an AI model of your self, now you may — type of.
On Thursday, AI start-up Hume introduced the launch of a brand new “hyperrealistic voice cloning” feature for the most recent iteration of its Empathic Voice Interface (EVI) mannequin, EVI 3, which was unveiled last month. The thought 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 shortly churn out an AI-generated duplicate of your voice, which you’ll be able to then work together with verbally, simply as you’ll with one other individual standing in entrance of you.
Additionally: Text-to-speech with feeling – this new AI model does everything but shed a tear
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 upset 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 characteristic
The imitation of my voice was, in some methods, undeniably life like. It appeared to pause intermittently when talking in roughly the identical manner that I are inclined to do, with a contact of acquainted vocal fry. However the mirroring stopped there.
Hume claims in its weblog put up that EVI 3’s new voice cloning characteristic can seize “points of the speaker’s character.” It is a obscure promise (most likely deliberately so), however in my very own trials, the mannequin appeared to fall quick on this regard. Removed from feeling like a convincing simulation of my very own habits 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 unusually staunch in its refusal to strive talking in an accent, which appeared to me like it will be the type of playful voice train that it will excel at. Once I requested it to provide an Australian accent a whirl, it stated “g’day” and “mate,” a couple of 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 artistic and roundabout approach to circle again to the subject I used to be discussing after I recorded my voice as a pattern for it to make use of, paying homage to an experiment from Anthropic final yr by which Claude was tweaked to grow to be obsessed with the Golden Gate Bridge.
In my second trial, for instance, I had recorded myself talking about Led Zeppelin, which I might been listening to earlier that morning. Once I then requested EVI 3’s voice clone of myself to elucidate its ideas on the character of darkish matter, it shortly discovered a approach to deliver its response again to the topic of music, evaluating the mysteriously invisible pressure pervading the cosmos with the intangible melody that imbues a tune with that means and energy.
You possibly can strive EVI 3’s new voice cloning characteristic for your self here.
In keeping with Hume’s website, consumer information produced from interactions with the EVI API are collected and anonymized by default so as to prepare the corporate’s fashions. You possibly can flip this off, nonetheless, via the “Zero information retention” characteristic in your profile. For non-API merchandise, together with the demo linked above, the corporate says it “could” acquire and use information 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 somewhat restricted of their realism; it’s totally apparent you are speaking to a robotic while you obtain responses from traditional 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 in addition, and extra importantly, to imitate the delicate inflections, intonations, idiosyncrasies, and cadences that inflect actual, on a regular basis human speech.
“A giant a part of human communication is emphasizing the proper phrases, pausing on the proper instances, utilizing the proper tone of voice,” Hume CEO and chief scientist Alan Cowen advised me.
As Hume wrote in a blog post on Thursday, EVI 3 “is aware of what phrases to emphasise, what makes individuals chuckle, 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 specialists would take umbrage with using 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 information, a course of that arguably does not go away any room for what we might acknowledge as true semantic comprehension.

EVI 3 was skilled “on trillions of tokens of textual content after which tens of millions of hours of speech,” in keeping with Hume’s weblog put up. In keeping with Cowen, this strategy alone has enabled the mannequin to talk in voices which are way more life like than would intuitively be anticipated. “With voice [models], what’s been most shocking is how human [they] could be simply by coaching on plenty of information,” he stated.
However philosophical arguments apart, the brand new wave of AI voice fashions is uncontroversially spectacular. When prompted, they’ll discover a a lot vaster vary of vocal expression than their predecessors. Firms like Hume and ElevenLabs declare that these new fashions can have sensible advantages for industries like leisure and advertising, however some specialists worry that they will open new doorways for deception — as was illustrated simply final week when an unknown individual used AI to imitate the voice of US Secretary of State Marco Rubio and subsequently deployed the voice clone in an try and 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, not too long ago advised me. “Like, what’s that for? Besides perhaps to disguise the truth that what you are listening to is artificial?”
Revolutionary turns into routine
Sure, EVI 3’s voice cloning characteristic, like all AI instruments, has its shortcomings. However these are considerably overshadowed by its exceptional qualities.
For one factor, we should always keep in mind that the generative AI fashions hitting the market at the moment 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 life like video and synchronized audio. The breathtaking tempo of generative AI developments ought to give us pause, to say the least.

In the present day, EVI 3 can simulate a tough approximation of your voice. It isn’t unreasonable to count on, nonetheless, that its successor — or maybe grand-successor — will be capable of seize your voice in a manner 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 a part of Zoom conferences in your behalf. It might additionally, much less optimistically, be a rip-off artist’s dream come true.
Maybe essentially the most putting truth about my expertise interacting with EVI 3’s voice cloning characteristic, 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 shocked earlier generations of people into awestruck silence. OpenAI’s Sam Altman made this very level in a current weblog put up: In keeping with Altman, we’re approaching the Singularity, but for essentially the most half, it looks like enterprise as typical.
