Local Language Virtual Assistant

Current virtual assistants only understand a very few major world languages. Some parts of the world are being left out and left behind. In an effort to provide options for other people who may not speak on of these major languages, we want to develop a regional voice assistant.
Scope out an action plan of steps needed to develop and roll out a local language virtual assistant (like cortana, alexa, Siri); first for a software based virtual assistant and then ultimately a hardware version.
