The phonology of vowel VISC-osity – acoustic evidence and representational implications

While vowel inherent spectral change (VISC) is becoming increasingly prominent in phonetic descriptions of varieties of English, there is little data on whether and how formant dynamics may shape the vowel systems of other languages. This paper provides cross-language acoustic comparisons of the degree of VISC in Polish and British English. In one study, British English showed a greater concentration of F1 movement earlier in the time course of vowels than Polish. In a second study, proficient Polish speakers of English showed a greater concentration of F1 movement earlier in the time course of vowels while speaking their L2 English than while speaking their L1 Polish. These findings are in line with a proposal formulated in the Onset Prominence (OP) framework, by which the relative degree of formant dynamics in the two languages is attributable to consonantal or vocalic affiliation of the Vocalic Onset (VO) node of structure. Consonantal VO affiliation in English contributes to a greater degree of VISC concentrated earlier in vowel duration. Further empirical patterns associated with the OP representational settings in the two languages are also discussed, along with implications for other languages.
