Spellchecker API is not working

[Niveshchandra]

Hi,

I used below code to perform spell check operation.

String[] dictionaryPaths = {"C:\\aem\\en_us.dic","C:\\aem\\en_us.aff"};

SpellChecker spellChecker = spellCheckerProvider.createSpellChecker("English",dictionaryPaths,resourceResolver);

But it giving exception like 

com.day.cq.spellchecker.SpellCheckException: No suitable dictionary found for language 'english'.

Can anyone please help me what is the parameter i need to give for language. I tried with en, en_us. No use with that also.

Thanks in advance.
