Dear ladies and gentlemen. I found myself in need of a detailed source of information regarding variants of pronouncing English sounds, and chanced upon this answer presented by tchrist several years ago:
The information given in this reply is exactly the kind I was looking for, however for the life of me I can't find either the original OED article or even the exact edition of OED where such detailed information on pronunciation is present. I would love to ask tchrist directly, however the site won't allow that. Could you please help me?
