Truecaller’s AI gets Microsoft’s new Personal Voice speech feature

Truecaller’s AI Assistant has just been upgraded with a new Personal Voice feature from Microsoft’s Azure AI Speech. Introduced back in 2022, Truecaller’s AI has been beefed up with many AI technologies over the years, many of them completely changing the user experience.

For instance, the app can automatically answer phone calls, screen calls, take messages, respond on the user’s behalf, or even record the call for later viewing. All these actions are possible thanks to Truecaller’s AI Assistant and many technologies it incorporates.

With the addition of Microsoft Azure AI Speech’s Personal Voice, users of Truecaller Assistant can create a digital version of their own voice to use inside the Assistant.

Basically, you’ll be able to have your caller hear a replicated and authentic version of your voice instead of one of the digital assistants on offer. According to Microsoft, watermarks will be added to speech outputs it creates to make it easier for a synthetic voice identification tool to verify them.



Furthermore, the Redmond-based company says that personal voice is a Limited Access feature available by registration only, and aimed at those who want to build apps around it.

A demo of the new feature has been demoed at Microsoft’s Build 2024 developer conference this month. Truecaller is an early access partner, so the app’s personal voice feature will be rolled out over the coming weeks in the United States, Australia, Canada, Chile, India, South Africa, and Sweden.
