@Robert Gentel,
You're just full of sarcasm tonight, aren't you. A phonetic standard, vis-a-vis orthography, is not at all the same as "differing phonological rules." Quite apart from that, i don't find passage convincing as a basis for your argument, because it doesn't state or imply that a lack of phonetic standard is a cause of there being dialects of English form which said differences of phonological rules derive.
What you sneer at as date dropping was offered to show that there can be a wide variance of phonetic usage over time, without making the dialects of a language mutually incomprehensible. Here, let me do it again, since it seems to irritate you. The French Academy was established in 1635. The French did not lose their North American colony to the English until 1760. The primary aim of the Academy from its inception was the standardization of the French langauge, grammar, syntax, pronunciation, orthography--and yet the French spoken in Canada differs so much that the patois of
les habitants is frequently referred to as
joual, which is the Québecois version of the word
cheval, meaning horse. It doesn't appear that phonetic standardization did much to assure that there would not be a diversion, and a radical diversion at that, in the language--which nevertheless remains mutually comprehensible as between Canadians and the French.
Frankly, i don't think the source you provided supports your claim, nor is an argument from authority conclusive in the matter of English pronunciation and orthography, which has had centuries to develop and diverge in disparate locations right across the globe, much of time in an absence of frequent intercommunication. As the French example shows, having such a phonetic standard will not assure that there is no divergence, so in particular, as regards the topic of this thread, i consider an argument on your part about a phonetic standard as being meaningless in assuring that there would ever be a simplified English orthography which would allow people to immediately recognize a word from the spelling to be a bootless argument.
Your expert writes of differing phonological rules as arising in part from dialect--so what explains the existence of dialect? Do you seriously believe that it would ever be possible to enforce phonetic rectitude? Do you not see the equal importance of what your expert source points to--" . . . phonetic interference between a foreign primary language and English?" As i have pointed out, the English language is "owned" by a lot more people than the native speakers of the language. You can chuck the old system of spelling, but anything with which you replace will be equally as arbitrary, and will very likely require just as much effort to assimilate for the non-native speaker, and very likely would induce a good deal of confusion in native-speaking children trying to figure out from context whether "yor" was the equivalent of what was once either your, you're or yore.
You sneers are entertaining, though.
