As a student growing up in France, I was always looking for ways to improve my English, often with a heavy French-to-English dictionary in tow. Since then, technology has opened up a world of new educational opportunities, from simple searches to Google Translate (and our backpacks have gotten a lot lighter). But it can be hard to find time and the means to practice a new language. So when the Web Speech API made it possible to speak to our phones, tablets and computers, I got curious about whether this technology could help people learn a language more easily.

That’s the idea behind Spell Up, a new word game and Chrome Experiment that helps you improve your English using your voice—and a modern browser, of course. It’s like a virtual spelling bee, with a twist.

We worked with game designers and teachers to make Spell Up both fun and educational. The goal of the game is to correctly spell the words you hear and stack them to build the highest word tower you can—letter by letter, word by word. The higher the tower gets, the more difficult the word challenges: You’ll be asked to pronounce words correctly, solve word jumbles and guess mystery words. You can earn bonuses and coins to level up faster.

Spell Up works best in Chrome on your computer and on Android phones and tablets. (It also works on iPhones and iPads, but you’ll need to type rather than talk.) Whether you’re just learning English or you’re already a pro, check it out! And if you’re a teacher, we encourage you to try it out in your classroom.
