Truecaller To Use Microsoft Azure AI Speech For Call Answering

Truecaller, a well-known app for identifying and blocking spam calls, is enhancing its services by allowing users to create AI versions of their voices. The new feature, available to those with access to Truecaller’s AI Assistant, stems from a partnership with Microsoft and its Azure AI Speech tool, allowing the generation of realistic AI voices that accurately mimic users’ speech patterns and tone.

“This groundbreaking capability not only adds a touch of familiarity and comfort for the users but also showcases the power of AI in transforming the way we interact with our digital assistants,” explained Truecaller product director and general manager Raphael Mimoun in a recent blog post.

The AI Assistant in Truecaller screens incoming calls, informing recipients of a caller’s purpose. Based on this information, users can decide whether to answer the call themselves or let the AI Assistant handle it.

When the feature was introduced in 2022, users could only choose from a collection of preset voices. The ability to record one’s own voice represents a significant step towards the complete personalization of the service.

Azure AI Speech, showcased during the last Build conference, only recently added a personal voice feature that lets people record and replicate voices. Microsoft explained in a blog post, however, that Personal Voice is available on a limited basis and only for specific use cases like voice assistants.

To maintain ethical standards, Microsoft’s Azure AI Speech automatically adds watermarks to AI-generated voices. Additionally, a code of conduct requires companies to obtain full consent from individuals being recorded and prohibits impersonation.
