You know about the old post on net.sources?
Have a look at some of the stuff in here:

It's the same vintage, may be of interest.
Also, I hacked the navy code around a bit to make it more
accurate and to assist with using a large phonetic
word list. And to parameterize the tables from an editable
data file rather than being hard coded in the C source.
I finally got a chance to dig through most of this code
(though some of your tables/wordlists are puzzling...
maybe "work in progress"?).
Did you derive the rulesets *directly* from the NRL
code or was it something you "inherited"? I find
several discrepancies between your rules and mine
and wonder if they are typographical errors *or*
improvements/enhancements you derived (my rules
mimic the NRL rules exactly).
The problem with this sort of algorithm is you're never
sure when it's "right" -- unlike an algorithm that
adds a column of numbers and prints a total! :>
The algorithm is considerably improved if you subject
the words
to TeX's hyphenation algorithm before applying the grapheme->phoneme
rewrite rules. Hyphenation points roughly correspond to phoneme
boundaries, and stop words like haphazard from sounding half-assed.
This makes perfect sense! Treat the word as "word-lets"
since sounds can't span a hyphen.
Where do I find this algorithm?
(sigh) Amazingly complicated for such a "simple" task... :>
Thanks!
