dictation in the wrong language

Yes it's so annoying! I have French, English and Spanish keyboards. When I dictate in English - and I have the English keyboard on - it writes down in French or Spanish gibberish, every other time! Same issue if I have the French keyboard on, I dictate in French and it writes down English nonsense etc. It's awful!

dictation follows the keyboard one has active so the more keyboards one have added the more languages one can dictate in
