The LEADTOOLS Advantage OCR engine comes with a default spellcheck dictionary consisting of words, phrases, and letter combinations. This dictionary can be extended by using the IOcrSpellCheckManager.AddUserWords() method.

https://www.leadtools.com/help/leadtools/v19m/dh/fo/iocrspellcheckmanager-adduserwords.html

This method accepts parameters specifying what language the words are in and an array containing the words to be added. Note only languages currently installed can have words added. The IOcrSpellCheckManager.GetSupportedSpellLanguages() method enumerates these and IOcrSpellCheckManager.IsSpellLanguageSupported() returns a value based on the specified one.

Here's a code snippet which shows determining a language is present and updating its dictionary accordingly:

Code:

         using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
         {
            ocrEngine.Startup(null, null, null, null);
            IOcrSpellCheckManager spellCheckManager = ocrEngine.SpellCheckManager;
            string en = "en";

            if (spellCheckManager.IsSpellLanguageSupported(en))
            {
               string[] wordsToAdd = { "LEADTOOLS", "OCR" };
               spellCheckManager.AddUserWords(en, wordsToAdd);
            }

            ocrEngine.Shutdown();
         } 


Note that the appropriate dictionary must be deployed for the language. We have these listed in our documentation on "OCR Files to be Included with your Application".
