A developer is working on a Chrome extension that provides real-time translated subtitles for video calls on platforms like Meet, Zoom, or Teams. The extension uses the Soniox speech-to-text and translation service, which costs $0.154 per hour, 17 times less than the previous solution using Deepgram and DeepL.

The extension's code and testing process are available, and the developer is open to feedback on improving the extension's performance.
