Description

In this challenge you have to recover the text being typed, just by analyzing the captured audio from the computer's microphone. The user is typing random English words. Only the English letters and the 'Space' keys are pressed (i.e. no Shift, Enter, Backspace, etc.).

All submissions that guess more than 95% of the text (i.e. 285 characters) are considered valid solutions and will enter the Hall of Fame below.
