Spelling errors are detected through the comparison of the keyed word with previously stored words of known spelling. The operator is immediately alerted upon the detection of a lack of comparison between the keyed word and the words available in the storage for operator consideration. When the operator is notified through an alerting device of a 'no match', the operator may then modify the spelling of the word if it is incorrect or accept the word if it is correct but not found in the dictionary storage. Words previously not located in the dictionary storage are then stored in a random access memory for subsequent use and the word most recently verified as correct and stored in the random access memory may be maintained at the top of a stack while the most infrequently used words will eventually be removed from the random access memory as the memory fills and overflows.

Spelling verification system with immediate operator alerts to

An electronic typewriter or other keyboard entry display device may have a voice or audio prompt option incorporated therein. The option provides for the operator to record a series of commands to position the print point as desired and then to code a series of characters spelling the word or words to be vocalized as a prompt. The recorded commands and the prompt may subsequently be played back to position the print point at a desired position on the page and the prompt vocalized to instruct the operator the nature of the entry for that position.
