The present study examined a variety of acoustic correlates to the stop length contrast in Finnish beyond the duration of the consonant itself. Of interest were the durations of surrounding vowels, the duration of voice onset time (VOT), and the amplitude of the release burst and the following vowel. Results indicated that for geminate stops, VOT is shorter and the amplitude of both the following vowel and the release burst are higher than for singleton stops. Further, long vowels preceding geminate stops are shorter than those preceding singleton stops, although no difference was found for short vowels. Post-consonantal vowel duration does not vary as a function of consonant length, but is affected by the length of the first-syllable vowel. These results agree with data from other languages in some respects, but not in others. It is proposed that this discrepancy arises from the fact that Finnish, despite being stress- or syllable-timed, also has mora-like length features.
