Google today released a new Chrome experiment called Spell Up, a word game designed to help improve your grasp of the English language using only your voice. You can try out what the company calls a “virtual spelling bee, with a twist” at chrome.com/spellup.

Since this is a Google project, Spell Up works best in Chrome on your computer as well as in Chrome on Android phones and tablets. Unfortunately, on Chrome for iOS you’ll need to type rather than talk.

Google says it worked with game designers and teachers to make Spell Up “both fun and educational.” The goal is simple: correctly spell the words you hear. As you do, they will stack up to build a word tower, and the higher it gets, the more difficult the word challenges become.

As the game progresses, you’ll be asked to pronounce words correctly, solve word jumbles, and guess mystery words. You can also earn bonuses and coins to level up faster.
