Which Texas accent? Does the writer not know that there are several regional accents in the state?
My thoughts too. There's quite a difference in some Texan accents.
I was born in El Paso in 1941, though I've lived in CA for the past 50 years, more than a few people still ask me about my 'southern' drawl.
Texan speech gets slower in ranching country and tends to sound more twangy depending on where in Texas you go. The folks in Lubbock talk slower than those in Abiliene, but Abiliene folks aren't near as hard to understand as some I ran into in Corpus Christi!
Funny thing - in Dallas there's a lot of ex-Californians, who always tag me as a local - though I've never been.
