How to deal with unsupported languages ​​in chatbot?

Question

Chats

Created chat/voice bot in Dialogflow and Amazon Lex. It works fine but I have some issues. For example, how to deal with unsupported languages.
Maybe there is a possibility to create a tool that could collaborate simoultaneously with such services like Google Dialogflow bot, Amazon Lex bot, Microsoft Azure bot. Main target is to get audio or text input from end-user, automatically detect langauge which he speaks (as an option: translate it by third-party service) and decide which bot service supports that language then send request to that bot service for further processing.
Much if appreciated someone could give me contact person that can answer my question
