The Conversation Translator provides a real-time language translation service for Lync instant messaging (IM) conversations.
With Conversation Translator, both the sender and receiver can converse in their native language, and Conversation Translator handles the translation. Powered by the Microsoft Translator Web Service, Conversation Translator currently supports translation between 35 languages.
So lets say I would like to engage in a conversation with my Finnish coworker Kristian Tuomilehto. Kristian is very fluent in english but for the sake of this demonstration he has agreed to reply to my Finnish IMs (Thank you Kristian).
After installing the tool, I just click the double chevron at the upper right of the Lync conversation window (see below) and choose Conversation Translator
The Lync client is extended with a conversation area to the right (see below) in which I can select sender and receiver language and start the conversation.
