AI Voice Cloning Apps Have No Consent Checks. None.

A Hong Kong company wired $25 million to fraudsters in 2024 because an employee trusted a voice. The voice belonged to the company's CFO. Except it didn't.

The clone was built from audio scraped off the internet, and it was convincing enough to move $25 million in a single transaction.

In January 2026, BGR covered a Consumer Reports investigation into the biggest AI voice cloning platforms on the market. ElevenLabs, Speechify, PlayAI, and Lovo, four of the most widely used services, have no technical mechanisms to confirm that the person being cloned has given consent. Anyone can upload a few seconds of audio and get a voice back. These are not fringe tools. They have millions of users, legitimate business customers, and polished interfaces built for podcasters and marketers. Consumer Reports found the same technology is wide open to anyone who wants to sound like your boss, your CFO, or your finance director.

The Numbers

Voice cloning now requires just 20 to 30 seconds of audio, and that audio doesn't have to come from a private conversation. A voicemail, a video posted on social media, a clip from a podcast interview, that's enough. The FTC reported that Americans lost $2.7 billion to imposter scams in 2023, and AI voice tools are accelerating the trend. Researchers at McAfee found that 77% of voice cloning scam victims lost money, with 36% losing more than $1,000. Human detection accuracy for cloned voices sits at 55 to 60 percent, barely better than a coin flip, according to researchers at University College London.

The playbook is simple. Scammers find audio of the person they want to impersonate, feed it into a cloning app, and call. No verification required, no consent check, no flagging system. They use the cloned voice to create urgency: "I'm in trouble," "I need money right now," "Don't tell anyone, just send it." The emotional pressure is designed to short-circuit judgment. When the voice sounds right, the brain wants to believe it.

What "Hang Up and Call Back" Doesn't Solve

The standard advice when you get a suspicious call is to hang up and call the person back on a number you already have. That step is worth taking, but a successful callback does not prove the original caller was legitimate. Sophisticated scammers can spoof numbers or manipulate context. For any request involving moving money or changing vendor details, verify through a second channel before acting, and if someone may be in danger, contact local authorities.

This is exactly the kind of request that Trust Onion's three rotating codewords stop cold. Before approving a wire transfer, changing vendor payment details, or acting on an urgent executive request, staff ask one question: "What are the words?" The codewords rotate every 60 seconds, calculated locally on each authorized person's device, with no server and no internet required. A clone can sound like your CFO. It cannot know three private codewords that change every minute and were never said out loud anywhere a microphone could hear them.

The Consumer Reports investigation made one thing plain: ElevenLabs, Speechify, PlayAI, and Lovo were designed for speed and quality, not consent. ElevenLabs added some restrictions after a 2023 backlash over fake audio of public figures, but restrictions are not verification. A policy buried in a terms-of-service document does not stop someone from uploading 30 seconds of a stranger's voice. Regulation moves slowly. The scammers using these tools are not waiting for a terms-of-service update.

The scam fails the moment the caller can't answer the question.

Frequently asked questions

How much audio does it take to clone someone's voice?

As little as 20 to 30 seconds of clear audio is enough for modern AI voice cloning tools to produce a convincing replica. That audio can come from voicemails, social media videos, or any public recording.

Are AI voice cloning apps legal?

Most voice cloning apps operate legally, but using them to impersonate someone for financial gain is fraud. The problem is that platforms like ElevenLabs and Speechify have no technical systems to verify consent before a voice is cloned.

How can I tell if a call is using a cloned voice?

You often can't. Human detection accuracy for AI-cloned voices sits at around 55 to 60 percent. The safest approach is a pre-arranged verification method, like rotating team codewords, rather than trusting your ears.

What should I do if I get a suspicious call from a family member?

Hang up and call the family member back on their usual number. If you can't reach them and believe they may be in danger, contact local authorities. A successful callback does not prove the original call was legitimate.

How do Trust Onion's three rotating codewords stop voice cloning scams?

The codewords change every 60 seconds and are calculated locally on each authorized person's device. A scammer using a cloned voice has no way to know the current words, so any caller who can't answer "What are the words?" is immediately exposed.

Give your finance and operations teams a simple two-factor check for high-stakes requests. Before any wire moves, staff ask "What are the words?" and a cloned voice will never have the answer, set up Trust Onion free at trustonion.io.
