This work aims to point out some relations between segmental
reduction and suprasegmental structures in Italian.
Following a previous study that observed an increase of reduction probability to occur after a pitch or nuclear accent in the tone-unit, we tried to verify the existence of relations between the amount of reduction and speech-rate variation in pre-accent and post-accent positions, introducing the notion of local speech rate (l-SR) as the pattern of the inverse values of syllable duration.
In a first stage, we classified three different l-SR patterns in the considered positions. In a second stage, we calculated the percentage of reductions occurring in each part of the scheme and the relation with the l-SR patterns.
Final results show that, although a coincidence of greater amount of reduction in post-accent positions with increasing tendency of l-SR does exist, it is not systematic; l-SR decrease is not able to inhibit reduction.
