I’m a NBT (native born Texan) and am proud of my accent. However, I have lived and traveled over a good bit of the world and have noticed that my accent has emulsified (I’m 74) over the years. It would be interesting to know where in Texas the sample was taken for the “Texas Accent” as Texas is a large state and as such has several regional accents within an umbrella Texas accent. I have to say though, being that the population of Texas has doubled over the past twenty years or so and throw into the mix of tv, internet, social media and so on the rural “howdy, where abouts y’all from” accent has all but disappeared. Anyway, y’all come see us, you hear? Lol....
I grew up in Texas then went into the Navy where I was stationed with guys from the northeast. I picked up on their accents. When I’d go back home on leave, people would tell me I talked like a Yankee. When I visited the northeast, people would say, “You’re from the south, aren’t you?”
I went on to live in Georgia, Canada, back to Texas, then to SoCal and NoCal. No idea what kind of accent I have, but someone once thought we had gone to high school together in San Francisco. Call me a mongrel.
