Google Translate recently added a number of new languages to online translation, including two local languages of Indonesia. The two local languages that Google translate presents in this offline translation are Javanese and Sundanese.
Javanese and Sundanese are among the 33 new languages present in Google Translate offline translation. These 33 languages can now be used offline on users' mobile devices.
This allows speakers of those languages to use Google Translate even when they don't have an internet connection. Most of the additional languages sound foreign. However, these languages are actually many users, especially in their own regions, such as Javanese and Sundanese.
