word pronunciation and synonym

AOA,
in a form i have placed one richtextbox now i want my application give me the Pronunciation and a synonym of word written in richtetbox
any one can help me in this regard

Synonyms are accessible through Microsoft.Office.Core:

VB Code:

Dim synonym As New Microsoft.Office.Interop.Word.Application
        Dim arr As Array
        arr = DirectCast(synonym.SynonymInfo("Yes").SynonymList(DirectCast(synonym.SynonymInfo("Yes").MeaningList, Array).GetValue(1)), Array)

You have to refernce word's COM object.

As for pronunciation, I think you're SOL. Even Microsoft Sam can't do that accurately. If you want though, you can set Microsoft Sam up to read the word to your user... But like I said, he's not very good.
