SING USER LEXICONS
(This section applies to Readiris Corporate only)
During recognition, Readiris is assisted by linguistic databases to
recognize text correctly. These linguistic databases are standard
lexicons and are available for every supported language.
As powerful as these standard lexicons may be, the recognition
accuracy can still be boosted using customized user lexicons. By
means of user lexicons, Readiris can recognize technical, scientific,
legal and company-specific terminology it would otherwise have
difficulty with.
To create and use a user lexicon:
 On the Settings menu, point to User Lexicon.
 Click Edit to open the User Lexicon Editor.
