  Identified particle spectra represent a crucial tool to understand the
behavior of the matter created in high-energy heavy-ion collisions. The
transverse momentum p_T distributions of identified hadrons contain
informations about the transverse expansion of the system and constrain the
freezeout properties of the matter created. The ALICE experiment has good
particle identification performance over a broad p_T range. In this
contribution the results for identified pions, kaons and protons in heavy-ion
collisions at 2.76 TeV center-of-mass energy are presented. These results are
compared with other identified particle measurements obtained by previous
experiments, and discussed in terms of the thermal and hydrodynamic pictures.
The status of extensions of this analysis, with the study of identified
particles as a function of event-by-event flow in Pb-Pb collisions, is also
discussed.
