This study sought to address three questions related to the pronunciation of Spanish by non-native speakers: (1) does the pronunciation of upper-intermediate become "fossilized?"; (2) is their a relationship between quality of pronunciation and amount of improvement?; and (3) when judging degrees of "foreignness," are linguistically trained native judges harsher than linguistically naive native judges? Eight intermediate learners of Spanish were recorded before and after a program in Spanish pronunciation, with 10 pairs of before and after sentences randomized and rated for quality of pronunciation by 4 native-speaking Spanish teachers and 4 native-speakers with no teaching or linguistic experience. The study found that although phonological fossilization was present in some subjects, it did not affect them in the same way. The results also indicated that some students benefitted considerably from pronunciation training, and that there were no significant differences in the ratings of linguistically trained and linguistically naive native judges. An appendix contains copies of a student language experience questionnaire, the rating scales, and the sample sentences. (Contains 39 references.) (MDM)
