Mixed-language teams are the norm on most frontlines. Translated voice and text would make a channel usable by all of it.
A yard with three shift languages currently solves this with whoever happens to be bilingual. That works until the day it matters most.
Translation needs text, and getting text from voice is transcription. We do transcription on the sending device precisely so the server never sees content — which means translation has to happen there too, or the encryption guarantee dies to add a convenience feature.
Quietly route your traffic through a translation service and keep the padlock in the interface.
