When vowel intrusion occurs between two consonants, the two consonant gestures are still coordinated with each other.
For instance, if vowel epenthesis occurs in complex codas, the maximal syllable for the language might be CVC.
Coda-repairing vowels are also subject to vowel harmony.
The Turkish vowel inventory contains eight phonemes distinguished by [±high], [±back], and [±round]; all three features are relevant to harmony, which affects most suffix vowels.

Studies in Articulatory Phonology (Browman & Goldstein, 1993) have established that what sounds like insertion of a segment can be a side effect of gestural timing relations.Like underlying vowels, epenthetic vowels are phonological objects, so they typically do not differ acoustically from underlyingly present vowels, and they generally participate in other phonological processes.In particular, epenthetic vowels crucially participate in syllabification, since they repair illegal syllable structures ().The inserted vowel in illegal coda clusters forms the nucleus of a syllable and allows the final consonant to be syllabified as a simple coda.Turkish stress placement is generally word-final, and like underlying vowels, inserted vowels in coda clusters receive stress when they occur in the final syllable.Studies in Articulatory Phonology () have established that what sounds like insertion or deletion of a segment can actually be a side effect of gestural timing relations.When the gestures for adjacent consonants do not overlap, a vowel-like interconsonantal interval can result.The resulting ) can be schwa-like or can ‘copy’ the quality of an adjacent vowel whose gesture overlaps the interval between consonants.Intrusive vowels contrast with lexical and epenthetic vowels phonologically, gesturally, and acoustically.But if vowel occurs, then the two final consonants are still part of the same syllable, and in some sense CVCC syllables are permitted.Finally, since intrusive vowels do not form syllable nuclei, they also cannot be targets for stress assignment.
