The OCR Tab
The options shown on the OCR tab window are for spellchecking scanned text, replacing missing or
unrecognized characters, and setting the speed and quality levels of the OCR processing.
1. Choose the options you want from the OCR window.
• Languages in Document—click on the language(s) in list that correspond to the languages
in the documents to be scanned. You can click on multiple languages. These are the
languages that will be recognized during the OCR process. For faster and more reliable
language recognition, select only the languages in the documents.
The languages are in alphabetical order. Type the first letter of a language’s name to jump to
its section in the list.
• Use languages and dictionaries to improve accuracy—select this option to automatically
check the validity of the recognized words. An OCR engine looks at each letter or symbol on
the page individually, then “guesses” what the letter or symbol is based on the shape.
Therefore, the OCR engine may have more than one guess for a particular letter or symbol, a
“best guess”, a “second-best guess”, and so on. This option tells the OCR engine to look
through the dictionary to validate its best guess for the letters in that word; if its best guess is
not in the dictionary, it checks for the second-best guess, and so on.
For example, if the word “house” appears in the original document but the OCR engine is
75% sure that the “o” is actually an “a”, the finished document would have the word “hause”.
Turning this option on tells the OCR engine to look at the other letters in the word, check to
see which version of the word is in the dictionary, and output the correct word “house” in the
final document.
The OCR engine does not automatically correct misspelled words that were present in the
original document.
When dictionaries are selected, the terms in those dictionaries are used to check the spelling.
If this is option is not selected, User Dictionaries and Professional Dictionaries cannot be
selected.
