Intelligent Spell Checker

I use NHunspell to check the line for such spelling errors:

var words = content.Split(' ');
string[] incorrect;
using (var spellChecker = new Hunspell(affixFile, dictionaryFile))
{
    incorrect = words.Where(x => !spellChecker.Spell(x))
        .ToArray();
}

This generally works, but it has some problems. For example, if I check the sentence “This is a (very good) example”, it will report “(very” and “good”) as sealed. Or if the line contains a time such as "8:30", it will report it as an error word. It also has problems with commas, etc.

Microsoft Word is smart enough to recognize a list of words separated by commas, time, fraction, or commas. He knows when not to use the English dictionary, and knows when to ignore characters. How can I get a similar, more intelligent spellcheck in my software? Are there libraries that provide a bit more information?

EDIT: I don't want to force users to install Microsoft Word on their computer, so using COM interaction is not an option.
