I‘m currently using Mira with the checklists from the German POHs for the planes I fly. This works surprisingly well when selecting a German Voice on iOS. The only situations where it sounds odd is when Mira tries to say something in English (like XXX ‘section’ or ‘checklist for’).
One disadvantage is that if I load a English checklist I manually need to switch the voice to an English one.
However, I now have a situation where things get ugly. I’m trying to include the S-TEC 55X preflight checklist in my Cessna checklist as one of the 172’s I will be flying is equipped with one. But this checklist is completely in English. So currently I have to add audio overrides to all texts trying to get the German voice engine to pronounce English correctly.
It would be much easier if we could instead select a voice per language and set a language for checklist as well as a override per section. This way, we don’t need to manually switch the voice when using different language checklist and having sections in different languages then the rest.
