The purpose of this paper is to offer acoustic evidence for an unusual phonemic contrast in Rome Italian. In our corpus, about half of all tokens of intervocalic /p t k/ are realized with uninterrupted voicing (both word-internally and across word boundaries). Furthermore, the voiced realizations of /t/ and /k/ do not significantly differ from /d/ and /g/ in duration and/or degree of constriction (as acoustically determined). Phonemic contrast is maintained under substantial phonetic overlap. Regarding the labials, duration keeps /p/ and /b/ apart. Contrary to the universal tendency, it is /b/ that is considerably longer, due to complex diachronic facts.
