Although expect it has a way to go yet........
Microsoft first released Skype Translator almost a year ago as a standalone app designed for Windows 8. The software giant is now integrating its impressive translation feature directly into the desktop version of Skype, opening it up to Windows 7, Windows 8, and Windows 10 users. Six voice languages will be supported at launch, including English, French, German, Italian, Madarin, and Spanish. Skype will now let you hold a conversation in any of them, without ever needing to learn a language.
