If you use Google Chrome, there’s a nifty little add-on you might want to check out, called Language Immersion for Chrome. It’s built using Google’s automatic translation services, so you can select from 64 different languages. It also allows you to select a level of fluency (from beginner to fluent). The add-on takes whatever web site you’re looking at and randomly replaces words with your foreign language equivalent. Clicking on them changes them to English, and hovering over them will give you a pronunciation.
It’s certainly not something that is going to replace serious study and reading target language material, but every little bit helps, and it’s a neat way to sprinkle some language exposure into your daily web routine.
