--UPDATE-- I just tried the feature again and found (or finally noticed...) the small drop-down arrow giving access to other languages. SO this means that probably most users will stumble on the same issue because even with French UI/keyboard, it defaults to English US. Word recognition with French (France) gave better results! But it still does not recognize the punctuation mark words.
My original post (below) did mention hilarious results that are obviously not as bad as I thought. So technically, it "works" but not as seamlessly as in English. I would then have this comment: if you can let us know how long users can expect before it gets improved in other languages, that would be helpful to answer their questions.
I did a quick test drive of the new Dictate feature yesterday and let's just say results were...hilarious?1?
I'm on V.1805 Build 9330.2014 Monthly Channel.
- In PowerPoint, "Titre de la présentation" (title of presentation in English), ended up in "Sit her down, please." LOL
- In Outlook, "Bonjour à toi - virgule" (Hello you, and the word for coma as punctuation mark), ended up in "Borschel at work with girl." ROFL
I tested with French keyboard, English UI. French keyboard and French UI: no luck.
But the few tests done in English were good.
Even though I am reporting this as an issue, I realise this is brand new and probably will get fine tuned. What can we tell users in terms of time required to make this feature work in another language!
