Thai Pali pronunciation / phonology?

Does anyone know of an article or reference work dealing with Pali phonology
in Thailand?  In other words, Thai pronunciation and mis-pronunciation of
Pali?

I would be interested both in any articles examining this from a purely
linguistic perspective, and in any materials looking at historical changes
over time.  It seems to me (as a purely unscientific observer) that quite a
bit of the modern pronunciation is attributable to confusion over the script
(i.e., the very different values that the same glyphs have in modern
vernacular usage) --but I would be interested to know more.

In case Thai subscribers to the list feel unfairly singled out: I read the
other day that the Burmese tend to recite Pali "ss" as "th" for similar
reasons --so this is hardly the only example of such confusion.

E.M.

The perfume of flowers blows not against the wind, not does the fragrance of
sandalwood, tagara and jasmine, but the fragrance of the virtuous blows
against the wind; the virtuous man pervades every direction.
