Yes, there are actually no irregularities in Spanish pronunciation. H is not pronounced and all the other letters have a corresponding sound. The rules of syllable stress are also very clear and if a word is stressed in defiance of the rules, there will be a written accent over the stressed vowel. You'll find a pronunciation guide to Spanish here: http://www.studyspanish.com/pronunciation/vowel_a.htm (There's also a difference between European Spanish and South American Spanish).
