The Web Speech API is the glue that holds everything together, considering without it, users today are unable to speak to their smartphones, tablets and computers. Using it to help folks learn a language more easily is nothing short of a stroke of genius.
Spell Up is a new word game and Chrome Experiment which intends to help you improve your English with your voice alone, although you would also need a fairly modern browser to get this pseudo virtual spelling bee up and running. Basically, the further you progress in the game by pronouncing words correctly, the harder and more challenging it will get. Spell Up would function best in Chrome on your desktop or notebook, as well as on Android smartphones and tablets. [Press Release]
