text: Vowels may be phonologically long or short (i.e. belong to the long or the short group of vowel phonemes) but their length is influenced by their context: in particular, they are shortened if a voiceless (fortis) consonant follows in the syllable, so that, for example, the vowel in 'bat' [bæʔt] is shorter than the vowel in 'bad'
