How Handheld Translators Work and Why They're Handy for Travel

WIRED 

Your cell phone can handle basic language translation, but bespoke tools can offer a much more immersive experience. Hans Christian Andersen once said, "To travel is to live," and while that's a romantic notion, he probably wasn't careening through Gyeongju, South Korea, at midnight in the back of a taxi with a driver who didn't speak a lick of English. Today's world traveler has it awfully easy when it comes to understanding the local lingo, as even a basic modern cell phone app can offer a pretty good translation of common phrases delivered in everything from Abkhaz to Zulu. Type or speak a sentence or two into the app, tap a button, and out it returns in the language of your choice. Tap another button, and your phone can even speak those sentences aloud.
