I was reared in Fort Worth, Texas.
I had no idea I had an accent, bad grammar or a Southern point of view . . . until . . .
My eighth grade teacher listened to my oral book report and gave me constructive criticism.
I was a shy child with a weird combination of inferiority complex and sense of superiorty operating simultaneously.
The teacher, Mrs. Greene, gave me six things I needed to work on and I was humiliated and furious.
I protested. She calmly suggested I go home and record myself reading a long, expressive passage out of a book . . .
and then LISTEN to myself--just to see if I continued to believe she had been too hard on me.
Well . . .
I did perform that experiment and I was apalled. I was shocked. I was hit hard to discover what a HAYSEED I was.
I was a poor White-trash, rural, Southern hick.
It was a blow.
I immediately embarked on a self-improvement program.
I memorized 16 new vocabulary words per day and wrote out the exact pronunciations indicated in the dictionary.
I found a person in school with perfect diction and had them listen to me when I read. I asked for corrections.
Example: "I'm going on a walk."
I would say it like this "I'm goin' own a wah-uk."
"Give me ten cents" would come out, "Gimme tin sints."
"I have a dent in my fender." would be "I have a dint in my finder."
My vowel sounds were all off.
Oil sounded like All.
Ignorant came out "Ig-nernt" and so on.
Within a 3 year period I had turned it around! It was the single most important improvement I've made to my life.
I regard a Southern accent now as being on a grayscale from "Charming to . . . stupid."
