Captio AI

Partial The UI and summaries can be built on existing speech-to-text and translation APIs, but dependable low-latency live captions across 60+ languages and noisy environments needs streaming ASR infrastructure and accessibility testing that vibe coding alone won't supply.

What it would actually take: Use a streaming speech-to-text provider (Deepgram, AssemblyAI, or Whisper-based real-time services) with a machine-translation API, delivered through a mobile or desktop client with WebSocket audio streaming. The hard parts are latency, diarization and accuracy across accents and noise, and testing with Deaf and hard-of-hearing users to meet real accessibility needs. That takes ASR and audio-engineering experience and ongoing evaluation work.
