As an aside, I have come across both Capernaum and Cafernaum, as names for that city.It all has to do with linguistics, and how sounds are created. p's b's and f's are thus related, and the usually get along well with each other especially at Christmas.
p - called a voiceless bilabial stop, while B is a voiced bilabial stop. Then you have the fricatives which I won't bore you with. :@)
We should also learn to speak slower. Thus we must adopt the slowest version of the Southern drawl which minimizes as much as possible the opening of one's cake hole. Having been around such speakers, it takes a genuine effort to understand what they are saying but have it easy to imitate myself, thus confusing locals into thinking I am a Southerner, which in spirit I very much am. So when I aspire to inspire whilst I cσnspιʀє while trying not to perspire lest the results be dire.
