finnish also denotes stress principally by adding more length (approximately 100 ms) to the vowel of the syllable nucleus. this means that finnish has five different physical lengths. (the half-long vowel is a phonemically short vowel appearing in the second syllable, if the first—and thus stressed—syllable is a single short vowel.) the unstressed short vowels are about 40 ms in physical duration, the unstressed long vowels about 70 ms. the stress adds about 100 ms, giving short stressed as 130–150 ms and long stressed as 170–180 ms. the half-long vowel, which is always short unstressed, is distinctively longer than the standard 40 ms.
