Truecaller AI Call Scanner Feature Launched to Prevent AI-Based Voice Scams: How It Works

Truecaller introduces a new artificial intelligence (AI)-powered feature aimed at helping users detect scam calls through AI. The Caller ID platform introduces an AI Call Scanner feature that can detect whether a person’s voice in a call belongs to a human or an AI. The company highlighted the increasing incidence of AI voice fraud, where bad actors use AI to invoke familiar voices to trick people. Notably, this feature will be available in the US first.

The newly announced Truecaller AI Call Scanner feature can analyze a caller’s voice in real-time and share the results within seconds, according to the company. To determine if a caller is using AI to scam the user, the AI ​​Call Scanner feature records the caller’s voice for a few seconds and then processes it using an internal AI model.

Truecaller says its AI model is trained to recognize the unique characteristics of human speech and distinguish it from AI-generated voices. It further adds that although the entire process takes a few seconds, it still maintains a high level of accuracy.

The feature will be available to Truecaller Premium users with the latest version of the app (version 14.6) on Android. The feature was first rolled out in the US, and the company said it will roll out in India and the company’s other major markets in the coming months.

The company noted that more bad actors are using AI that mimics human voices to try to extort money from victims. By sampling human voices from social media videos to train the AI, the voice is then used to call victims who are related to those whose voices were cloned.

Scammers use a familiar voice when calling their victims, who fall for the scam because it is designed to sound similar to the voice of their relatives. Truecaller points out that these scams were first noticed in 2019, and that they have grown exponentially in the following years.
