What it heard
Translation
ar-SA does not work. Krisp lists Arabic (Saudi Arabia) but its streaming service
rejects it, as source and as target. It is disabled in the picker. Use ar-XA
(Standard) or ar-EG (Egypt). There is no Iraqi or Gulf code at all.
Turnaround is mostly sentence length. Krisp will not translate until it decides a sentence has ended, so a long sentence turns around slowly. The translate step stat separates the two: it measures only the gap between the sentence closing and the English being ready. In our tests it is near zero, so the wait is sentence detection, not translation. Speak in short sentences and the delay drops.
Krisp has no end-of-stream message, so Stop sends 1.5 s of silence to close the last sentence.
The cost number multiplies mic seconds by the rate in the box. That rate came from Krisp's website and nobody has checked it against a real bill.
Your mic needs localhost or HTTPS. Both are fine here.
