Local Real-Time Subtitles on Ubuntu with Moonshine and Pympress

Language barriers remain a significant challenge in international conferences. Not all speakers are fluent in English, and even when they are, their speech may not always be easy for diverse audiences to understand. While some events provide professional captioning or simultaneous interpretation, such services are not always available for every session.

In this talk, I will present a self-contained approach that enables speakers to generate real-time subtitles directly from their own laptop. By combining Moonshine Voice, a lightweight and efficient speech-to-text (STT) system that can run even on devices like Raspberry Pi, with Pympress, a PDF-based presentation tool, we can build a fully local, automatic subtitle system on Ubuntu.

This approach allows speakers to make their talks more accessible without relying on external infrastructure or services, making it easier to participate in international events regardless of location or available resources.
