Beware! Unmasking Audio Deepfake Scams: How to Spot AI-Generated Voice Impersonations

Defending Against Audio Deepfake Scams: How to Detect AI-Generated Voices Impersonating Your Loved Ones

In a world increasingly dominated by technology, even our senses can be deceived. Deepfake technology, driven by artificial intelligence (AI), has become a powerful tool for scammers to manipulate audiovisual data and create fake voices that sound remarkably real. Imagine receiving a voicemail from your Mom, urgently asking for money because she forgot her bank password. Would you rush to help her?

Audio deepfakes are a rising concern as they can convincingly impersonate people's voices and emotions, leading to serious consequences. With just a few recordings, scammers can craft deceptive messages to trick victims into sending money or divulging sensitive information. In this article, we will explore the major signs of an audio deepfake and provide essential tips to safeguard against falling prey to such scams.

Signs of an Audio Deepfake Recording:

#1. Poor Elocution:

At present, the simplest sign of an audio deepfake is noticeable slurring and poor articulation. Deepfake software relies on a dataset of recordings to fabricate human speech. If the software lacks a specific phrase or word, it may struggle to generate natural-sounding speech. However, as technology advances, this flaw may diminish as datasets become more extensive and sophisticated.

#2. Distracting Background Noise:

Deepfake scammers often use background noise to conceal the artificial nature of the voice. Intentional background noise, such as static or interference, can be a telltale sign of a deepfake. With advancements in microphone technology, modern devices produce clear audio without any old-school walkie-talkie-like noises. Constant warping, crackling, or whirring in the background could indicate an audio deepfake.

#3. Unnatural Speech Patterns:

Humans are inherently expressive beings, and our emotions are evident in our speech patterns. Thus, unnatural phrases, tones, and vocabulary are red flags for an audio deepfake. Deepfake recordings often lack emotional depth, sounding flat and monotonous. If someone is in a stressful situation, their speech should reflect the heightened emotions. Unusual or suspicious expressions and vocabulary suggest that an AI is attempting to imitate human emotions but falling short.

#4. Impossible Vocal Noises:

While synthesized audio is incredibly challenging for us to detect, AI can easily spot one significant mistake made by deepfakes. Human anatomy imposes a minimum possible separation between vocal noises, which means we physically cannot jump from noise to noise any quicker. When deepfakes overlook this limitation and create impossible vocal noises, their robotic nature becomes evident.

Safeguarding Against Audio Deepfakes:

Trusting your ears to detect these subtle signs might not be foolproof, so let's explore two proven methods of prevention:

AI Detection Tools:

Thankfully, AI-powered voice verification tools already exist and can analyze audio recordings even in the presence of background noise. Utilizing machine learning, these tools can identify discrepancies and recognize deepfakes. With up to 48,000 data points in each second of a 48kHz recording, AI can analyze even low-quality recordings effectively. In the future, AI-based voice and video verification software will play a crucial role in cybersecurity.

Cyber Hygiene:

Prevention is the best defense against cyberattacks. By adopting strong cyber hygiene practices, you can fortify your digital security. Consider the following:

  • Use strong passwords and change them frequently.
  • Invest in premium antivirus and firewall software.
  • Encrypt data during transit using a reliable VPN (compare Nord vs Surfshark options first).
  • Keep all software up to date to patch vulnerabilities.
  • Implement Multi-Factor Authentication (MFA) for added security.


While the day may come when we can't distinguish between human and synthetic voices, for now, we can still identify audio deepfakes. Equipped with AI voice verification tools and knowledge of the signs mentioned above, you can protect yourself from falling victim to deepfake audio scams. Staying informed and practicing good cybersecurity measures are essential steps to safeguard your digital well-being in this rapidly evolving technological landscape. Remember, knowledge is power, and by being vigilant, you can stay one step ahead of the scammers.
