Bitonal pitch accent and phonological alignment in Sardinian

This study presents new data on pitch accent alignment in Sardinian, a Romance language spoken in Italy. We propose that what has been described as "stress shift" in encliticization processes is not a change in the word level stress, but variation in the association of the pitch accent. Our claim is that word level stress remains in situ, and the falling tune which our data exhibit can be interpreted as a bitonal pitch accent (HL*) associated with the entire verb + enclitic unit: the starred tone is associated with the rightmost metrically prominent syllable, and the leading tone is associated with the word-level stressed syllable. The research questions we address are twofold: (i) how are the landing sites of the two tonal targets phonetically identified; (ii) how are the phonetic facts reconciled with prosodic structure.
