Could you build this?
Partial Basic web-based transcription and translation is easy via APIs, but outputting low-latency live broadcast-quality NDI video streams alongside synchronized multi-device client feeds requires specialized AV streaming infrastructure.
What it would actually take: The backend requires low-latency WebSockets or WebRTC ingesting live audio, routing through real-time streaming speech-to-text (e.g., Deepgram) and machine translation pipelines with sub-second latency. For the venue display, it requires a native desktop or server application integrating the NewTek NDI SDK to render and broadcast the subtitle video feed over local networks to production switchers. Achieving broadcast-grade reliability, low latency, and NDI protocol compliance requires specialized audio/video systems engineering.
