During the talk, based on collaborations with V. Gayral, C. Levy, A. Sitarz and D. Vassilevich, different aspects of the Connes--Lott action and Chamseddine--Connes spectral action for spectral triples are developed. New results concerning the second action for the noncommutative torus and the triple associated to SUq(2) are presented.
