UVTAbout the developer
UVT is built and maintained by Mehdi Golzari, an independent software developer. UVT is free and open source, and it will stay that way.
Work with me
If your company needs something like UVT, built around your own product, team or customers, I can help design and build it. For example:
Real-time translation
Live speech-to-speech translation and subtitles for meetings, support calls, sales calls, classes or events, in the languages your users speak, including right-to-left languages like Persian and Arabic.
Voice AI in your product
Connecting realtime voice models (such as Google Gemini Live or OpenAI Realtime) to your web app, browser extension or call flow, with low delay, reconnects and clear privacy.
Chrome extensions
Private or public Chrome extensions for your team, built for Manifest V3 and ready for Chrome Web Store review: permissions, privacy disclosures and testing included.
What UVT shows
- Audio capture, resampling and pitch-preserving speed control in the browser (Web Audio, AudioWorklets).
- Two-way translation inside live web calls without reconnecting the call (WebRTC).
- One extension that works with more than one AI provider, chosen per direction.
- Privacy by design: no servers, keys stay in the browser, clear consent.
- A bilingual English and Persian interface, with automated tests in a real browser.
The whole source code is public on GitHub, so you can see how it is built.

For help with the UVT extension itself, please use the help page or GitHub issues. Contacting me is never needed to use UVT, and UVT never sends me any of your data.
