Allophones 1 Pre Fortis Clipping Vowels Phonetics Phonology Loạt video clip về một số allophones trong tiếng anh như được giới thiệu trong sách english phonetics and phonology của peter roach. mình bổ sung. The pre fortis clipping process arises from the fact that the length of a vowel is strongly determined by the voicing of the consonant that comes after it (or by the absence of any consonant, if this is the case). the term fortis is equivalent to voiceless and clipping stands for shortening. so, what this convoluted expression means is that.

Notice that (1) is already sufficient to reflect the phonotactic constraint that disallows the occurrence of short vowels finally in a stressed syllable. better is ˈbet.ə rather than * ˈbe.tə not only because the t triggers pre fortis clipping and is tappable, but also because a syllable ˈbe would not be phonotactically well formed.
