I am making an app in Actions on Google. It was working fine on English language . I need to make it work for Japanese also. But as I have read in google docs I understand that we can create same app supporting multi languages which will be shown in Dialogflow. But as per my knowledge these languages are switched with respect to the default language selected in the google home. For example, if the Home is in Japanese language it will be invoking the Japanese version. I want to know is there any method to change language by its invoke call or by asking first question about the preferred language? Please anyone give a right way to get these things done.
My app is still under testing. Not yet published.
