The accent Latin America's coasts inherited from the ships that left Seville and Cádiz. Seseo, s aspirated to a breath, d dropped between vowels and at the end, final r and l blurred or lost. It is the fastest-sounding Spanish because so many consonants are gone.
Where: southern Spain, Cuba, Puerto Rico, the Caribbean coast
The way in: 'Estoy cansado' as ehtoi kansao.

Anything the spelling engine can transcribe, the accent can move. Slow it down to hear the shape.
Quick and clipped, with the weight on the vowels because so many consonants are missing. Rising tails on statements in the Caribbean.

In the order the mouth applies them. Every before-and-after is playable — click the IPA. The pattern is the rule as the engine runs it, for the curious.
Consonants
The θ becomes s
θ → s
How: A plain s. Tongue tip behind the teeth, not between them.
Seseo. The whole of Latin America, and Andalusia, never had the lisped c. It is a Castilian innovation of the 1500s that the colonies left before it arrived.

Accent
cinco
zapato
casa
unchanged — 'casa' and 'caza' are now one word
ll and y become one sound
ʎ → ʝ
How: Say y as in 'yes'. The tongue does not touch the roof of the mouth along the sides.
Yeísmo. The palatal l of the spelling survives only in parts of the north and the Andes; everywhere else it has become the y of 'yo'.

Accent
calle
now identical to 'caye'
lluvia
s weakens to h before a consonant or at the end
s(?=[pbtdkɡqʔmnɲŋɴfvθðszʃʒɕʂʐçxχɣʁħʕhβʝlʎɹrɾjwɥʈɖɳɽʋɦ]|$| ) → h
When: when no vowel follows the s
How: Breathe out through the s position without touching. A soft English h.
The s is still there in the speaker's head; the tongue just does not reach it. Listeners from Madrid hear 'los' as 'lo' with a breath.
