I have a very versatile voice and can do numerous accents in both English (N.American) and Spanish with no accent carryover. I can also do Radio News quality readings in both English and Spanish. I can do accents in both English and Spanish that range from professional to heavily regional and can handle impersonating most accents in both languages.
My first language is spanish, but I have no trace accent when speaking English, which has been described as West texan. I can do most dialects in Spanish such as Mexican, Border Mexican, Southern Mexican, Puerto Rican, Cuban, Spaniard, and most others without much prep. In English, I can impersonate most accents such as Eastern (New York, Boston), South (Texas drawl, country), and can do most accents such as Indian, Arabic, English (European), Scottish/Irish (they sound surprisingly similar when I do them for some reason). Please note that these accents lean more towards the comedic than the serious. For professional presentations, my best languages are English (N. American, middle age)and Spanish (Central Mexico, educated, middle age).
