My students tend to find it hard to believe that I'm a local native and my friends seems a little too quick to assure me that I don't have much of a Southern accent (like sharing a regional dialect with the likes of William Faulkner, Sidney Lanier, and Harper Lee is a shameful thing), but there are still some lingering pieces of my upbringing that bug me a little. I find it quite impossible to say the word "jewelry" unless I really concentrate as I work my way through the word. It tends to come out more as "jewry" or "jury", both of which are entirely different. I'm pretty sure that wearing Jewry is illegal or, at best fairly tasteless. Both Jewry and jury would be a little cumbersome. Another troublesome word is "architect." This one is perhaps even more embarrassing, if just for the fact that I have to be careful that it doesn't come out as "AR-key-tek," which makes me sound a bit like a hillbilly. I also feel self-conscious with the word "Italian," although I'm pretty sure I always pronounce it "ih-TAL-yun" and not "EYE-tal-yun." The good news is that I haven't pronounced words like "bell" with two syllables since something like the third grade.
To still confuse matters, some words I'm quite proud to pronounce in the vernacular fashion. I refuse to pronounce "pecan" as "puh-CON". I stress the first syllable (a distinctly Southern habit) and then pronounce the vowels by the vowel-consonant-vowel pronunciation rule (which I'm aware is more of a suggestion when talking about the English language, but it does give me the rhetorical high ground).
And there are some other words that I have trouble saying but for no reason of culture. I'm a stutterer, although a partially recovered stutterer thanks to years of speech therapy in grade school. It only shows through in occasions of strong self-consciousness and certain words and word combinations. If I'm nervous, especially about the prospect of stuttering, I'll get stuck on certain sounds, my name being a particularly difficult phrase when meeting new people (something I'm almost always uncomfortable with.)
There are those really rare words or combinations of words that I will always get stuck on regardless of my comfort in the situation. "Sweet potato" is nearly impossible for me, and I have no clue why. Sadly I really like these and will order them frequently in restaurants, especially with a steak which leaves me to gag on the words or to arrive at the order in some circuitous manner. I really wish it were possible to avoid communicating with the spoken word entirely.
