TalkBridge
Two people, two devices, two languages. Speech is streamed to a Pipecat tunnel that transcribes, detects the language, translates and speaks it to the other side.
Everyone hears everyone, each in their own language. Every station needs the same room code. Each thing anyone says is translated once per language in the room — three people reading three languages is three times the work of three people reading one.
Open /a on one machine and /b on the other, with the same room code. No sign-in required.
