This investigation examines different measures of oral fluency for second language learners of Spanish in three different learning contexts: formal or at home (AH); intensive overseas immersion (IM); and study abroad (SA). A total of 25 participants divided equally in five groups participated in the study: AH1, AH2, IM, SA, and a Spanish NS group for a baseline comparison. The data analysis focused on the 15 longest turns produced by each participant in a 30-40 minute sociolinguistic interview. Results indicate that no learner group was proven to be superior with regard to all fluency measures. In terms of rate of speech, ratio of filled pauses per syllables, and percentage of syllables in repetition per total syllables, the IM group was shown to be superior. As for number of spoken words, total number of seconds per turn, and percentage of syllables in repair per total syllables, the SA group was shown to be superior.
