words spelled the same, pronounced differently

[Jill Brandon <jilcol@TENET.EDU>]

I'm sure somebody out there knows this.  What is the term for words that
have the same spelling, but are pronouned differently, based on their
meaning?  Words suce as "resume" - to start again, and "resume" - a list
of qualifications.  Or read - present tense and read - past tense.  Where
could I get a list of such words?
Thanks a bunch!
