The vocalisations of the Italian sparrow are similar to those of both the Spanish sparrow and the house sparrow. Its vocalisations carry better in natural environments than those of the house sparrow. The male gives a "chreep" call like that of the Spanish sparrow to proclaim nest ownership, and a faster version of this as part of courtship display. Male song patterns grade slowly into those of the Spanish sparrow across southern Italy, but in the area of overlap between the house and Italian sparrows, the two birds sound alike.
