Captions, or a voice, come some seconds after the speaker.
Most likely: normal delay
Check: the lag next to each channel in the Console. It is how long that channel takes to follow the floor's newest caption.
Fix: a few seconds behind is normal on every channel. Recognising the speech, translating it and, on a voiced channel, saying it out loud each add a moment.
Next: one channel is behind and keeps falling further behind
Check: the channel's lag keeps climbing. From 3 s, its language code and lag turn amber; from 15 s, they turn red.
Fix: on an AI voice channel, open the channel's ⋯ menu and select Restart this channel. Its listeners hear nothing for a few seconds, captions resume from the live edge, and the backlog is discarded, not caught up. Other channels have no restart: note the time and contact support if the lag keeps climbing. See Voices in the Console.
Next: a slow connection on the Console computer
Check: the connection badge at the bottom right shows Slow or Poor.
Fix: improve this computer's connection: a cable, or a seat close to the router. See The connection badge.
Still not working
Note which channels are late and by how much, and contact support with the time and the session.
