In 2024, fraudsters pulled off one of the most chilling deepfake scams yet:…
They cloned the voice of WPP’s CEO, staged a fake Microsoft Teams meeting, and convinced an employee to authorize a $25 million transfer.
Believing they were speaking with trusted executives, the employee approved the payment.
By the time the fraud was discovered, the money had already been moved through offshore accounts and was gone.
The most terrifying part?
The scammers only needed 90 seconds of the CEO’s voice, taken from public presentations and earnings calls, to pull it off.
It is so scary.
But there’s a solution to every problem, and in this case, the solution is the best AI voice detector free tools that can instantly analyze and verify voice authenticity.
In this blog, we’ll cover what an AI voice detector is, how it works, and its key benefits.
You’ll learn how it differs from generic audio analyzers, the best free AI voice detector and the step-by-step instructions of using the tool.
Let’s dive in.
Key Takeaways:
- An AI voice detector is a tool that checks if a voice recording is real or made by AI. It finds small patterns in the audio that people can’t hear but AI voices usually leave behind.
- Undetectable AI is one of the best detectors. It is free, works in your browser, and gives quick and reliable results.
- Regular audio tools only check sound quality or background noise. AI voice detectors are different because they are built to catch fake or cloned voices.
- Since it runs in the browser, you don’t need to install anything. It’s easy to use and helps you confirm in seconds if a voice is real or fake.
What Is the AI Voice Detector?
- Definition and Core Purpose
An AI voice detector is a tool that helps you find out whether a voice is human or was created by artificial intelligence.
This free AI voice detector technology has become increasingly important as AI-generated voices are everywhere these days such as in YouTube videos, social media clips, or even scam calls.
It’s scary to think someone might use your voice to commit fraud, and then you’d have to prove you did nothing wrong.
Never Worry About AI Detecting Your Texts Again. Undetectable AI Can Help You:
- Make your AI assisted writing appear human-like.
- Bypass all major AI detection tools with just one click.
- Use AI safely and confidently in school and work.
For example, in 2024, the engineering firm Arup was tricked into transferring millions after fraudsters used a deepfake video call.
The scammers impersonated the company’s CFO and other executives with fake voices and images. The employee sent around HK$200 million (roughly US$25 million) to accounts controlled by the attackers.
With just a short voice sample (sometimes under a minute), someone can clone a voice convincingly.
That’s where our free best AI Voice Detector comes in. The tool analyzes a clip’s pitch, tone, and rhythm, then compares what they find against known patterns of synthetic voices.
As a result, it gives you probability if the voice is real or AI-generated.
- Who Should Use It
Our free AI voice detector online is useful for both organizations and individuals:
- High-stakes users: CEOs, bankers, lawyers, politicians, and journalists who are often targeted by scams or misinformation.
- Organizations: Contact centers, customer-service teams, and banks use them to stop fraudsters pretending to be real customers. Businesses rely on them to avoid financial losses and protect their reputation.
- Everyday users: Anyone who receives voice messages can benefit from a free AI voice detector. For example, a suspicious WhatsApp note from a “family member” can use a detector to check if it’s genuine or AI-generated.
In short, anyone who deals with voice recordings and values authenticity should use our best AI voice detector free tool.

Best Practices for Using AI Voice Detector
Here are some best practices to get the most out of our best AI voice detector tool:
- Always Analyze Audio in Full Context
Our free AI voice detector online is powerful, but it shouldn’t be your only check. Always consider the bigger picture:

This approach is recommended by security experts, and it builds a stronger defense against fraud.

Train employees and stakeholders to question suspicious voice clips even if they sound familiar.
Unusual requests, odd wording, or poor timing should all raise concerns. Regular awareness training makes our free AI voice detector online far more effective.
