When working with the LEADTOOLS OCR SDK you have the ability to recognize many languages other than English. The SDK supports more than 40 different languages and you can see a list of some of the languages here:

If you are wanting to recognize more than the English language, then you can call "EnableLanguages()" inside of the OCR language manager. Here is a small code snippet as to how you would do this:


using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false)) 
      // Start the engine using default parameters 
      ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir); 

     //Enable German
     ocrEngine.LanguageManager.EnableLanguages(new string[] { "de" });

    //Check current enabled languages
    string[] enabledLanguages = ocrEngine.LanguageManager.GetEnabledLanguages(); 
    Console.WriteLine("Current enabled languages in the engine are:"); 
    foreach (string language in enabledLanguages)

This code snippet can also be found under the IOcrLanguageManager Interface here:
