The OcrSpellCheckEngine.Native spell checker is used differently depending on your OCR engine type:

For OcrEngineType.Plus and OcrEngineType.Professional, this is the native spell checker that ship with the Professional and Plus OCR runtimes.
For OcrEngineType.Advantage, LEADTOOLS will use Microsoft .NET WPF spell checker. Current dictionaries support is: English, French, German and Spanish only. Leadtools.Forms.SpellChecker.Native.dll is required and the Microsoft .NET Runtime 3.0 or later must be installed on the machine.

The OcrSpellCheckEngine.Hunspell is only supported by LEADTOOLS Advantage OCR engine and uses the uses the popular Hunspell spell checker (through the standard .NET NHunspell wrapper). LEADTOOLS setup does not contain the NHunspell binaries or any language dictionaries. You must download the required assemblies from the NHunspell page as well as the dictionaries for the languages you are interested in. Visit the NHunspell home page at http for more information.

Any language supported by both OCR Advantage and NHunspell.
