Same missing language layer here, from Italian. No language setting in Grok Bot, and typed Italian still reads like English then translated. We posted the longer report under Dean Rie on the Portuguese voice thread: [Grok Bot] Voice dictation in Portuguese arrives as English text
A picker would help. Even without one, the bot should follow the thread language as we go. Tracking this together with the STT path would help more of us actually work in a language that is not English.
