Also it's possible to change Recognition language ant chat level. Just click microphone and settings button. To be able operators to do this to operators role has to be assigned "Speech module" -> "Allow operator to change chat recognition language"

Also then you click plain microphone button Chrome will ask you permission to access your microphone. For operators be able to use this feature in general to them has to be assigned "Speech module" -> "Allow operator to use speech recognition module"

Why does chrome each time asks for permission to access my microphone?

This is chrome policy once message is send I stop listening and start listening again to avoid same message continous translation. This can be avoided if chat is using HTTPS just like our demo site.
