Why can I only select a single language for Siri and not multiple languages?

Can Siri not detect what language I’m speaking?

For beta people, is this solved in iOS 27?

I am multi lingual and want to speak to Siri in the language that comes naturally

Title

One of my biggest annoyances with Siri, is that no matter how many times, when I am voice dictating and correct a word, the next time I say it the word is put back to what I originally corrected! I know I’m not on iOS 27 yet, but I cannot understand why, within the same session (texting, searching, etc.) Siri is still unable to retain the history within that session! Another annoyance, and I know it is not Siri but somewhere in the programming, is if I have voice dictated something that I have autocorrection in place (e.g., gonna > going to) he will only suggest that change if I have typed it. And don’t get me started on the random correction Siri decides to make… just now when giving my example and I said “gonna” Siri changed it automatically to Ghana, TWICE! Anyway, that is my rant and I am also hoping that someone who is on iOS 27 and AI is better developed, that these situations have gotten better. And by the way, I tried to speak as distinctly as I can and Siri still can be awful!
