This is really beyond the scope of HTML.

How to say a particular word is normally handled by Text-to-speech  
systems, and is one of the things that distinguishes good ones from  
ordinary ones. There is a specification called SSML being developed by  
the Voice group, and currently in Candidate Recommendation:  

You could use XSLT to provide SSML styles for particular pronunciation.  
The Pronunciation Lexicon seems to be low on the priority list for the  
Voice group at the moment, but could also play a role.

(Linking a lexicon is the sort of thing that people have complained  
about as entirely impractical, or have suggested is a good way to  
approach the problem of using clear language...)
