Truecaller Unveils AI-Powered Voice Assistant for Personalized Call Handling

As AI continues to transform various industries, including the displacement of voice agent roles, companies are now venturing into replicating human voices through synthetic means. Truecaller, the renowned caller ID service, has embraced this trend by introducing an AI-powered Assistant that can answer calls using the user’s own voice.

This innovative feature is made possible through a collaboration with Microsoft, enabling Truecaller to utilize the Redmond giant’s Personal Voice technology, which was unveiled in November as part of Azure AI Speech.

By leveraging Microsoft’s Personal Voice technology, Truecaller’s Assistant, accessible to premium subscribers, gains the ability to mimic users’ voices for greetings and responses during calls. This complements the existing preset system-generated voice options available through the digital assistant, which can handle tasks such as answering calls, screening unknown numbers, taking messages, responding on behalf of the user, and recording calls.

To activate this feature, Truecaller users simply need to record a brief script in their own voice after granting consent. Subsequently, the Assistant can commence answering calls with the digital version of the user’s voice.

While Truecaller’s Assistant typically allows users to modify the introductory greeting template for callers, the company has confirmed to TechCrunch that this option is restricted when using the personal voice instead of a system-generated one. This measure ensures callers are aware they are interacting with a “digital” representation of the user’s voice.

However, users can still customize follow-up responses based on their preferences. Additionally, Azure AI Speech’s personal voice feature, currently in limited registration-only access, incorporates watermarks into generated speech outputs for detection by a specialized tool, identifying synthetic audio.

Raphael Mimoun, product director and general manager of Truecaller Israel, expressed confidence in the personal voice feature revolutionizing call management for users, stating, “We firmly believe that the personal voice feature will revolutionize the way our users manage their calls and elevate their overall experience with Truecaller Assistant. We look forward to further exploring the potential of AI-powered voice technologies in partnership with Microsoft and delivering even more innovative solutions to our global user base.”

The rollout of the personal voice feature on Truecaller’s Assistant will commence in the upcoming weeks, initially targeting the U.S., Canada, Australia, South Africa, India, Sweden, and Chile. Public beta users will have first access, followed by a broader release to all users in eligible markets.
