This document discusses the production of final voiced stops in English by native Spanish speakers. It explains that Spanish does not have words ending in voiced consonants like /b/, /d/, or /g/, so Spanish speakers' brains are not trained to recognize these sounds. As a result, they may pronounce words like "cab" as "cap". The document recommends that to properly pronounce final voiced stops in English, Spanish speakers should lengthen the vowel sound before the stop, which will allow their vocal cords to vibrate and produce the voiced sound correctly. It provides examples of English words ending in each voiced stop for Spanish speakers to practice.
