In this review we describe and discuss recent results on the linear dielectric response of high permitivity dielectric ceramics in the frequency range 102-1014 Hz. For these materials the polar phonon spectra are discussed together with their flow-frquency dielectric response and dispersion regions in between, in the 10-300K or higher temperature range, depending on the existing phase transitions of interest
