Why latency matters
When the speaker's words and the caption drift several seconds apart, attendees end up reading and missing the talk. barotalk uses OpenAI's combined real-time speech-to-text-to-translation engine as-is, and our broadcast server only relays it, so it adds almost no extra delay. It's a setup proven at real events every week.
