Skype announced Monday that it plans to have Skype Translator ready by the end of summer. Skype Translator is currently in its preview version and supports four spoken languages, Venture Beat reports.

Skype Translator is a real-time translation technology Skype wants to add to the Skype for Windows app by "the end of summer 2015."

The preview version of the app supports four spoken languages -- English, Spanish, Italian and Mandarin -- and 50 written instant messaging languages.

Skype Translator relies on machine learning. That means the more the technology is used, the better the translation services will become.

Last month, Skype removed the preview sign-up requirement for Skype Translator. After that requirement was removed, Skype said that it has seen a 300 percent increase in the use of Skype Translator. At this rate, the translator may be able to quickly improve. 

Skype Translator is currently being offered as a separate app and that is said to be a good thing since it might not work well in its early stages. The preview app has only been available for six months. 

Since Skype Translator was only released for Windows, having it added to the Windows desktop app first makes sense. Other versions of the app were not announced Monday. 

Versions of Skype Translator could eventually come to Linux and Mac as a separate app or they could be integrated right into the Skype app. A Skype Translator app for Android, iOS and Windows Phone likely will not come for quite some time. 

The end of summer release of Skype Translator lines up well with the upgrade to the latest Windows operating system Windows 10 July 29. According to The Verge, Microsoft is starting to preview a new version of Skype for Windows 10 to partners. Microsoft plans to preview its new Skype for Windows 10 to the public in the coming weeks.
