The study examines the pronunciation of Czech /ɪ/ and /iː/ in the speech of Czech Radio newsreaders. This vocalic contrast has been traditionally described as consisting in duration. The analyses reveal that the duration of the phonologically long /iː/ is only approximately 30% greater than of the phonologically short /ɪ/. As for the analysis of formant values, the short /ɪ/ appears to lie closer to vowels of the /e/-quality than to its long counterpart /iː/. The morphological status of the syllables with /ɪ/ and /iː/, as well as the position within an utterance have been taken into account. The result also indicate interesting idiosyncratic tendencies.
