that via evolution and heredity changes, latin american or spanish people have developed certain differences in their jaw and connecting muscles associated with speech due to the different pronuciation of the latino or spanish language that makes it difficult to enuciate certain english words correctly....
that is another reason why it's sometimes hard to understand their speech....in addition to the speed and increased number of syllables of the forementioned languages.
