First... Yes... I did put this in Feedback under Cortana
Cortana in Canada is still failing miserably !!! Please... Microsoft Engineers escalate this !!!
The Default Language for Canada is set as French (Canada) and Cortana is insisting on Speaking French and even if the English(Canada) speech packs are downloaded and installed and then selected.... Cortana still will not speak as she wants to download something. Not sure what. And it isn't French (Canada).... as that downloaded automatically despite the fact I don't speak French and haven't since High School... 45 years ago !! And I can't get rid of it.
Now if you had set the Default Speech to Spanish (United States) for the Region United States... then you would have exactly the same problems !!
Also if I do select English (Canada) in the Cortana>Settings) it loses ALL Languages in the drop down and Cortana crashes !!
Only 23.2% of our population uses French (2011 census). 75% use English as their primary language. This is now 5 Builds that Cortana has failed!! Perhaps if ALL your people in the Microsoft Centre in Vancouver had English (Canada) as their default then you might act a lot faster... eh? (<- It's Canadian)
The only way to get Cortana to Talk is to set the Region/Language/Speech all to English (United States). And frankly we would rather be Canadian these days !!
