Mexico
Northern Mexican Spanish, spoken across Sinaloa, Sonora, Chihuahua, and Nuevo León, features clear consonant articulation and open, distinct vowels — final 's' is never aspirated or dropped as in Caribbean dialects, and intervocalic consonants are fully pronounced. The region's proximity to the US border produces significant English contact, with loanwords and code-switching common in everyday speech. Northern Mexican Spanish uses 'tú' for second-person singular (no voseo), and the accent is often described as slower-paced and more clearly enunciated than central Mexican or Caribbean varieties.
