Partial The UI for side-by-side bilingual captions is buildable, and speech-to-text and translation APIs can be wrapped. However, capturing system audio reliably on Windows and keeping live transcription and translation low-latency and accurate across speakers is harder.
What it would actually take: Build a Windows app that captures system audio via WASAPI loopback, streams it to a streaming speech recognition API (or a local Whisper model), then sends segments to a translation API and renders both languages in a live two-column view. The hard parts are latency, speaker separation, and handling domain terminology for interpreters. This requires audio engineering and speech-pipeline experience.
