Abstract

This paper compares the acoustic phonetic appearance of voiced & voiceless geminate stops in Sienese Italian. In our spontaneous speech data voiceless geminate stops are frequently preaspirated, which is an extremely rare phenomenon cross-linguistically. Preaspiration of voiceless stops has been associated in other languages with devoicing of voiced stops. We compare the acoustic appearance & duration of voiceless /VC:/ sequences (with & without preaspiration) with voiced /VC:/ sequences in our language. Results indicate that long voiced stops in Sienese Italian are often partially devoiced – a phenomenon that has not been reported previously for any variety of Italian. We suggest that preaspiration & devoicing are likely related, & attempt to provide an articulatory explanation as to why they occur.
