The lowest of the low? Based on consonant pronunciation? How can you extract a value judgment from how someone speaks?
I was born in Castile, so I usually speak "accentless" standard Spanish, but my mother comes from Extremadura, just a couple hours drive to the south, and when I speak to her I involuntarily switch to the extremaduran accent. I don't notice it but other people hearing me for the first time are shocked by the sudden switch.
Extremaduran accent has the same aspirated x and s mentioned in the article, so for "This is Extremadura" I'll tend to say "Ehto é Ehtremaura" to my mother and "Esto es Extremadura" to other people. Another curiosity is that many of the original "conquistadores" (Cortés, Pizarro) hailed from Extremadura.
The lisp always sounds odd to me. That and vosotros. The vast majority of Spanish speakers worldwide use neither.
za, ce, ci, zo, zu -> tha, the, thi, tho, thu. As in 'think'. That's it.
My slightly younger cousin’s friend found the way I pronounced things as well as some of my vocabulary to be very funny. When I pointed out that he also had an accent he almost almost wet himself with laughter, so absurd was the idea to him that both of us had accents rather than the one of us who didn’t sound American.
I mean it’s not exactly uncommon. I have the luck of having a southern U.S. accent and I’ve been told (mostly by people from outside the US in fairness) that they were surprised I wasn’t a raging racist.
It's worse in some places than others but it's practically universal.
In Argentina they call spaniards gallegos, like from Galicia, the Spanish region north of Portugal.
Do you have an example of omiting vowels between consonants? IMO the whole Spain speaks quite fast.
Reventado -> Reventao Colocado -> Colocao
On vowels between consonants, maybe "tarántula" -> Trántula spelling it really fast in a hurry.
But what I meant with the Andalusian accent being really fast and omiting vowels, they do in a way pretty close to the Southern US English accent.
Also, the Andalusians got a lot of arabisms (more than former Spanish) such as zaguán, babuchas, alcancía, alhaja, alcoba... the same way the Southern US English got lots of borrowings from Spanish.
