American English rhymes involving laterals have been shown to exhibit coordination patterns reserved for onsets (Marin & Pouplier, 2010; Katz, 2012). These results, however, were based solely on items with lax vowel nuclei. There is evidence, based on limited data and simulations, suggesting that this pattern may not extend to rhymes involving tense vowel and diphthong nuclei (Popescu, 2019; Hsieh, 2017). In this talk we present data systematically comparing duration and formant dynamics across different vowel type nuclei (lax vowels, tense vowels, diphthongs) and postvocalic sonorant consonants (laterals, nasals).  Results show that vowel-consonant (VC) timing in American English rhymes are modulated by both vowel type and morphological composition.
