Perception and production of the short and long Finnish [i] by 17 Finnish-speaking subjects was studied. First, 19 vowels varying in F2 were categorized either as [y] or [i]. Four durations were used: 50 ms, 100 ms, 250 ms, and 500 ms. The F2 value of the category boundary was independent of duration at group level, although large individual variation occurred. In the subsequent vowel rating experiment the subjects scored the quality of their individual [i] category variants. All subjects were able to score the category best exemplar (prototype), and the worst exemplar (non-prototype). Mean scores for prototypes were independent of duration.
   In production experiment, the articulation of the Finnish words [tikki] and [tiili] was recorded and the duration and F2 of the short and long [i] vowel were analyzed. The F2 values of the individual auditory vowel prototypes did not correlate clearly with the F2 values of the articulated [i] vowels.
