Phase 2 of the Vesper project, a biometrics-based voice communicator, is nearing completion. During this phase, we worked on creating audio stream augmentation technology. We wrote about what this augmentation is here https://biometriq.pl/en/voice-stream-augmentation-what-is-it/

Our proprietary voice stream augmentation engine is currently undergoing perceptual (listening) and blind testing. Their goal is to provide an objective evaluation to confirm proper engine operation in line with the established quality parameters. Furthermore, the built-in voice stream augmentation technology in the voice messenger is designed to aid in detecting unauthorized voice use for further synthesis/conversion without causing degradation of sound to the human ear. This is all to prevent voice theft and ensure the most effective service performance.

It’s worth noting that solutions on the market such as SKYPE, ZOOM, DISCORD, Google Meet, TEAMS, WhatsApp, Signal, Threema, Viber, and Telegra do not support biometric caller authentication.

We are pioneers in this regard.

The comprehensive project completion is scheduled for September 2026.

In the first stage of the project, we mainly tested the far end voice stream source authenticity algorithm, which we informed you about here https://biometriq.pl/en/tests-of-a-voice-communicator-with-a-source-authenticity-detection-module-are-underway/

Project financed by EU funds.

Are you curious about the final solution?

Phase 1 of the Vesper project is nearing completion. We’ve launched a test version of the messenger with an implemented far-end voice stream authentication module. Tests are being conducted on three different environments: Windows, Android, and iOS. The results are consistent with the project’s KPIs. We’re working to ensure that quality indicators not only meet the design minimums but, where possible, exceed the established goals. Our priority is to develop a product that meets user needs and builds a positive user experience.


We conduct experiments based on 40 speakers, 20-second recordings, testing each recording across 5 channels, and obtaining over 171,500 embeds. This number of recording configurations is designed to help achieve the target parameters, confirming the effectiveness of our messenger.

Vesper Messenger is intended to be a response to the growing problems of cybersecurity and identity theft.
