Abstract: An open environment for a real-time multilingual communication environment for text-based and voice conversations in a variety of different languages and/or for multilingual machine-generated or machine-carried text exchanges in a variety of languages. The users send their messages in their own spoken languages and the recipients receive in real-time the messages translated into their spoken languages. The open environment provides links to a variety of the online real-time translation services available on the Internet or on other network and controls real-time translation by selecting the best translation services for translations, which are specific to the theme of the communication session and to the number of languages needed for translation in the session. The users are communicating in different natural languages with the real-time translation to the language designated by each user.
