The universal translator remains in the realm of science fiction, but Google Translate is a decent (if relatively rudimentary) alternative for international travelers seeking basic information in foreign lands. This free app translates text between 64 languages. With 17 of those languages, you can speak a word or phrase instead of typing it. And in 24 languages, you can listen to your translations spoken aloud. Google Translate may not replace UN translators anytime soon, but it's a handy way to ask for directions to the nearest railway station.
