Siri used to be great for voice dictation on my iPhone 6. All worked well. One day, though, she started misunderstanding one specific sentence, namely "à la ligne" (new paragraph, in French). since then, she transcribes by writing "/" instead of actually starting a new paragraph.

I tried resetting her database (turning here on and off in setting, as well as "voice dictation"), but nothing works.

Any idea what's wrong, and how to fix this?

Thanks!
