The purpose of this study was to investigate changes in the pronunciation and intelligibility of instructed and uninstructed second language (L2) learners over time, and to identify instructional, environmental, and methodological factors playing a role in pronunciation and intelligibility. / Seventeen L2 graduate students at an English-medium university recorded three personal anecdotes over five months. The students also regularly logged their exposure to and use of English. Nine of the students (instructed group) were concurrently taking an oral communication course focussing on suprasegmental pronunciation. Classroom instruction was regularly observed and recorded. All 17 students were interviewed at the end of the study. / L1 listeners heard anecdotes from three instructed and three uninstructed students, matched for length of residence and first language (L1). Listeners also heard anecdotes from four L1 English speakers. One group of listeners retold each anecdote after hearing it (discourse-level task). The other group paused the recording of each anecdote whenever a word was unclear (word-level task). Each group of listeners also rated excerpts for accentedness, comprehensibility, and fluency. / Results of quantitative and qualitative analyses showed that: (a) no unambiguous changes in the pronunciation or intelligibility of either L2 learner group occurred over time; (b) word-level intelligibility measures more consistently differentiated L1 and L2 groups, and the instructed and uninstructed L2 groups; (c) compared to the instructed group, the uninstructed group logged relatively more English exposure/use for academic activities and relatively less for interactive social activities; (d) many instructed L2 learners did not believe that their pronunciation had noticeably improved, but almost all expressed satisfaction with their ability to communicate in English; (e) at the end of the study, many uninstructed learners reported persistent difficulties in communicating in English. / The results suggest that instruction in suprasegmental aspects of pronunciation sometimes may not lead to improved intelligibility or pronunciation. In addition, some L2 learners can be as intelligible as L1 speakers, depending on the listening task. Finally, results suggest that L2 learners' perceptions of their communicative ability and their patterns of L2 exposure/use are related. Implications for university preparation and support programs for L2 graduate students are discussed.
