the disclosure describes an overall system / method for developing a “ speak and touch auto correction interface ” referred to as staci which is far more superior to existing user interfaces including the widely adopted qwerty . using staci a user speaks and types a word at the same time . the redundant information from the two modes , namely speech and the letters typed , enables the user to sloppily and partially type the words . the result is a very fast and accurate enhanced keyboard interface enabling document production on computing devices like phones and tablets .
