# ContextCheck

A Boolean value that specifies whether to improve the accuracy of OCR, by checking recognized words against one or more dictionaries that are chosen based on the value of the Languages parameter. When context-checking is enabled, Media Server expects text to have conventional capitalization, use of numbers, and punctuation - for example numbers would not appear in the middle of lowercase words.

In most cases OpenText recommends using the default value, `ContextCheck=TRUE`.

In cases where the source text contains unusual or specialized words that do not appear in a dictionary, set `ContextCheck=TRUE` and `Languages=ASCII`, which does not use a language-specific dictionary. If necessary, you can expand the character set by setting the parameter ExtraEnabledCharacters.

Only set `ContextCheck=FALSE` when you are recognizing unusual text that resembles a random sequence of characters.

Dictionaries that you specify with the parameter UserDictionary are always used, regardless of the value of this parameter.
