I am using actions on google with api.ai. I am able to create a api.ai bot in a language other than English, but the web simulator of actions-on-google (https://developers.google.com/actions/tools/web-simulator) seems to work in English only? Is there any option to change the language there or a time schedule when other languages (in my case German) will be available in the simulator?
Currently testing a non English action is impossible, because the web simulator does not even forward requests if it doesnt understand their meaning on its own.
Update 09/08/2017: Google Home is now available in Germany, I just bought one. Isn't it possible to test my German actions with a google home device either?
Yea -- sorry, you need to set your phone to US-English to test today. We are working on making Actions on Google work for German but that will likely not be ready until later in the year.
AoG is now only available in en-GB an en- US. As Adams said you have to wait for a year.
Any progress here?
While we could build a skill including linking accounts with Amazon Alexa in a day for de_DE, en_US and en_GB the same seems impossible in Google Home atm.
