Don't speak English, French or ...
Found an interesting app for iPhone and iPad that I wish that I had when we were in Indonesia. You speak a phrase into your machine and it translates it into the other language. It is not perfect, but pretty good. We tried French, German, and Chinese. The translation is spoken and printed on the screen. It will also back translate to English to make sure it worked.
You can go from English to 19 other languages. The app is free for use if you are connected to the Internet. If you want it to work offline, which you would, it is $5 for each language.
Oops, almost forgot the name. It is called Jibbigo. Might be worth checking to see if there is an Android version.
In South Africa doing lots of boat stuff. Departure north from Cape Town around December 15th. Arrival in the Caribbean around the beginning of February, after 5300 miles or so.
