Truecaller announced a partnership with Microsoft to utilize the new Personal Voice technology from Microsoft Azure AI Speech. Truecaller's AI Assistant, first introduced in September 2022, already incorporates a multitude of AI technologies that can automatically answer phone calls for user, screen calls, take messages, respond on behalf, or record the call for user later viewing. With the addition of Microsoft Azure AI Speech's Personal Voice, users of the Truecaller Assistant can now create a completely digital version of their own voice to use inside the Assistant.

This means that if user already have Assistant on user Truecaller app, user can have callers hear a replicated and authentic version of user voice instead of one of the many digital assistants on offer. Truecaller is the early access partner for Personal Voice and a working demo for this new feature has just been showcased at the Microsoft Build conference in Seattle.
