Truecaller launched AI scam call detection in US

In order to tackle AI scam calls, Truecaller unveiled an AI call scanner that made its US premiere. In order to prevent frauds, the function evaluated callers' sounds in real-time and distinguished between voices produced by AI and those of humans. It is available to Android subscribers of Truecaller Premium and attempts to counter the rise in AI voice scams, in which con artists impersonate well-known voices in order to trick their victims.

 The newly announced Truecaller AI Call Scanner feature can analyse the voice of the caller in real-time and share the results within a few seconds, according to the company. In order to identify whether a caller is using AI to scam the user, the AI Call Scanner feature records the caller's voice for a couple of seconds and then processes it using an in-house AI model. The AI model is trained to identify the unique characteristics of human speech and distinguish it from AI-generated voices.

The company highlighted that multiple bad actors are using AI that mimic human voices to try and extort money from victims. By taking samples of people's voices from social media videos to train the AI, the voice is then used to call victims who are related to those whose voices have been cloned.

The scammers use a familiar voice when calling their victims, who fall for the scam as it is designed to sound similar to the voice of their relatives. Truecaller points out that these scams were initially spotted in 2019 and have risen exponentially in subsequent years.

The feature is first being rolled out in the US, and the company said it will be introduced in India and other major markets of the company in the coming months.
