AI can clone voices and create convincing fake videos. What businesses need to know about the risks, legitimate uses, and how to protect yourself.
AI Voice Cloning and Deepfakes: The Business Implications You Can't Ignore
In February 2024, a finance worker in Hong Kong paid out $25 million after a video call with "senior management." Everyone on the call was a deepfake.
This isn't science fiction. It happened. It's happening more.
If you run a business, you need to understand this threat—and the legitimate uses that exist alongside it.
What's Actually Possible Now
Voice Cloning
Quality: Near-perfect replication of any voice with 30 seconds of sample audio. How enterprises should think about deploying such technologies is covered in our enterprise AI guide.
Tools: ElevenLabs, Play.ht, Resemble.ai, many others.
Cost: $5-50/month for consumer tools.
Time to create: Minutes.
What you can make:
- Someone saying anything in their voice
- Real-time voice conversion during calls
- Emotional variations (happy, sad, angry)
- Multiple languages in the same voice
Video Deepfakes
Quality: Convincing for video calls, less convincing for high-res footage.
Tools: Various open-source and commercial options.
Cost: Free to hundreds per month.
Time to create: Hours for basic, days for polished.
What you can make:
- Face swaps onto other bodies
- Lip-synced video to any audio
- Full synthetic video of a person
Real-Time Deepfakes
Quality: Good enough to fool people on video calls.
Tools: Exist but less accessible.
Threat level: This is what enabled the $25M fraud.
Live video manipulation during calls is possible. Not perfect, but convincing enough.
The Threat Landscape
CEO Fraud (Evolved)
Old version: Email pretending to be CEO requesting wire transfer.
New version: Voice call or video call with deepfake CEO making the same request.
The email version has a ~3% success rate. Voice calls are significantly more convincing.
Vendor/Client Impersonation
Scenario: "Client" calls to change payment details. Voice matches perfectly because it's cloned.
Accounts payable sends payment to fraudulent account.
Reputation Attacks
Scenario: Deepfake video of executive saying something offensive. Released before it can be debunked.
Even when proven fake, damage is done.
Blackmail
Scenario: Fake audio/video of someone in compromising situation. Demand payment to not release.
Proving it's fake doesn't matter if it goes viral first.
Internal Manipulation
Scenario: Fake voice message from boss approving something that shouldn't be approved.
Bypass controls by impersonating decision-makers.
Real Incidents
$25M Hong Kong Fraud (2024)
Deepfake video call with multiple fake participants convinced employee to transfer funds.
$243K UK Fraud (2019)
AI-generated voice of CEO directed fraudulent transfer. One of the first reported cases.
Political Deepfakes (Ongoing)
Fake videos of politicians making statements. Election interference concern globally.
Romance Scams
Deepfake video "proving" someone is real in online dating/romance scams.
Legitimate Business Uses
Not all voice cloning is fraud. Legitimate applications exist, though they must comply with emerging AI regulations:
Content Efficiency
Use case: Clone your own voice to generate content faster.
Record once, generate many variations. Localization without re-recording. Consistency across content.
Example: A course creator clones their voice to generate multiple versions, corrections, and updates without re-recording everything.
Accessibility
Use case: Generate audio versions of text content.
Convert written content to audio for accessibility. Create audiobooks at scale.
Example: A company uses voice synthesis to create audio versions of all documentation.
Personalization at Scale
Use case: Personalized video/audio messages.
Generate thousands of personalized messages that sound human.
Example: A sales team uses voice cloning to create personalized video messages at scale.
Entertainment and Media
Use case: Character voices, dubbing, voice restoration.
Film dubbing, game characters, preserving voices of historical figures.
Deceased Voice Preservation
Use case: Memorial or historical preservation.
With consent, preserve voices of loved ones or historical figures.
How to Protect Your Business
Verification Protocols
For financial transactions:
- Multi-factor verification for any transfer request
- Out-of-band confirmation (call them back on known number)
- Codewords or phrases established in advance
- Multiple approvers for large amounts
For sensitive decisions:
- Verify through secondary channel
- In-person confirmation for major decisions
- Question unexpected requests regardless of apparent source

Frequently Asked Questions
How easy is it to clone someone's voice with AI?
Very easy. Modern tools like ElevenLabs can create near-perfect voice clones with just 30 seconds of sample audio, costing as little as $5-50/month. The process takes minutes, making voice cloning accessible to anyone with basic technical skills.
Are deepfake video calls really convincing enough to fool people?
Yes. The February 2024 Hong Kong incident where a finance worker transferred $25 million after a deepfake video call proves they're convincing enough for fraud. While not perfect for high-resolution footage, real-time deepfakes on video calls are good enough to fool people, especially when combined with urgency and social engineering.
What should my company do to protect against deepfake fraud?
Implement multi-factor verification for all financial transactions, establish out-of-band confirmation procedures (call back on known numbers), use codewords or phrases established in advance, and train employees to question unexpected requests regardless of who appears to be making them. Never rely on voice or video alone for high-stakes decisions.
Is it legal to clone someone's voice?
The legality varies by jurisdiction. Generally, cloning your own voice or someone else's with their explicit consent is legal. Cloning without consent falls into a legal gray area in most places, though laws are emerging. Using voice clones for fraud is clearly illegal everywhere.
Can deepfakes be detected reliably?
Detection technology exists but lags behind generation capabilities. High-quality deepfakes can fool current detectors, and detection accuracy decreases as generation technology improves. Never rely solely on detection tools - use procedural safeguards like verification through alternative channels.
What are legitimate business uses for AI voice cloning?
Legitimate uses include cloning your own voice for content efficiency, creating accessible audio versions of text content, generating personalized messages at scale, and media production like dubbing or character voices. The key is using the technology with consent and transparency.
The Bottom Line
AI voice cloning and deepfakes are real, accessible, and being used for fraud today. The technology will only improve.
For defense:
- Trust but verify (through alternative channels)
- Multi-factor verification for anything important
- Train your team
- Update your processes
For legitimate use:
- Clone only with consent
- Disclose synthetic content
- Don't deceive
This isn't future risk. It's current reality. The $25M loss in Hong Kong won't be the last. Make sure it's not your organization next.
