 The general expectation is that syllables with long stressed vowels followed by short consonants have a higher vowel:consonant duration ratio, while syllables with short stressed vowels followed by long consonants have a lower vowel:consonant ratio. However, a great many other factors affect the relative duration in any one recorded token. See Pind 1999, 'Speech segment durations and quantity in Icelandic' (J. Acoustical Society of America, 106(2)) for a review of the acoustics of Icelandic vowel duration.
