SakiRinn/LiveCaptions-Translator

Lightweight and powerful real-time audio/speech translation tool based on Windows LiveCaptions.

What it solves

LiveCaptions Translator provides real-time speech translation for Windows 11 users. It bridges the gap between Windows' built-in Live Captions (which provides transcription) and translation services, allowing users to understand audio from videos, games, or live streams in their preferred language without needing a Copilot+ PC.

How it works

The tool integrates with Windows Live Captions to capture real-time audio transcription. It then sends this text to a selected translation API—such as LLM-based engines (Ollama, OpenAI, OpenRouter) or traditional services (Google Translate, DeepL)—to generate translated subtitles. These translations are displayed in a highly customizable, transparent overlay window that can be embedded into the screen to avoid interfering with other applications.

Who it’s for

Windows 11 users who need real-time translation of system audio or microphone input, specifically gamers, students attending online lectures, and professionals in meetings.

Highlights

  • LLM-powered translation: Supports LLM-based engines for better context handling and incomplete sentences.
  • Immersive Overlay: A borderless, transparent window that can be fully embedded into the screen for an unobtrusive experience.
  • Broad API Support: Compatible with a wide range of services including self-hosted (Ollama, LibreTranslate) and cloud-based (OpenAI, DeepL, Google).
  • History Management: Records original and translated text with the ability to export records as CSV files.
  • Fluent UI: A modern interface that automatically switches between light and dark themes based on system settings.
