This study explores how fundamental frequency (F0) and articulatory strength are related in Italian geminate consonants. Consonant-intrinsic F0 (CF0) effects are examined with a focus on the hypothesis that geminates exhibit such effects as a consequence of their inherent “tense” articulation, manifested as higher F0 and a more constricted articulatory target. Simultaneous articulatory and acoustic data were collected from 10 native Central and Southern Italian speakers pronouncing six disyllabic nonce words ([ip(ː)a, ib(ː)a, im(ː)a]) within a carrier sentence varying in speech rates. F0 values were extracted at 10 ms intervals before and after consonantal closure, while articulatory data, including Minimum Lip Aperture (LA) and Maximum Jaw Height (JH), were recorded using an AG501 Carsten EMA. Linear mixed-effect regressions were fit to the data. The findings reveal that geminates exhibit higher post-closureF0, lower LA, and higher JH compared to their singleton counterparts, supporting the hypothesis that geminate consonants possess “tense” properties. Additionally, weak positive correlations were observed between post-closure F0 and LA.
