This whole thread has one fatal weakness : No one knows what the “real’ pronunciation was thousands of years ago. Language always changes. No one has even an inkling how Moshe rabbeinu prnounced his words. Teimani Hebrew may be the most approximate (as one poster said) because they lived the most isolated life for many years.Not only the pronunciation but also the actual language. The neviim had different words than the Torah- just read the neviim! and the mishneh had its own words too. If there were changes in the actual words, “al achas kammah vekammah’ on the pronunciation. And, lastly, every person who did not speak hebrew as a first language is influenced by the pronunciation of the first language- whether it is yiddish, french or german. Hence, there is “holy’ proninciation.
