This is actually a follow up question to Cortana error "I'm sorry, but I can't speak your language" in Canada
I am following Microsoft's document http://www.windowsphone.com/en-ca/how-to/wp8/cortana/cortana-alpha and installed latest Preview for Developers. I think I have met all requirements.
It is later than 8.10.14214.329 as needed.
English Canada is the first one in list.
Canada is my region.
English US is the speech as required.
With all the settings when I run Cortata I still got error message
I'm sorry, but I can't speak your language.
