In a recent press release, Microsoft said it is introducing the 129th language, Lower Sorbian, to the Microsoft Translator translation application. This is an endangered language that is currently spoken by less than 7,000 people worldwide.
Wikipedia introduction is as follows:
Sorbian, also known as Wendish, is the language of the Sorbian minority in southeastern Germany and belongs to the West Slavic branch of the Slavic language family.
The language is divided into Upper Sorbian and Lower Sorbian, with Lower Sorbian mainly found near the German state of Brandenburg. It is a critically endangered language with fewer than 7,000 speakers.
Microsoft has announced its Translator Microsoft Azure Cognitive Service to further protect the language by supporting translations to Lower Sorbian in a variety of scenarios, including documents and web pages.
