In this paper a method for speech quality evaluation of TTS system is presented and its usability is assessed. The ITU-T P.563 is used as a reference-free objective measurement method for speech sequences synthesized by concatenative TTS system. The method was examined and the achieved results were compared to those measured by subjective auditory tests and their correlation values were observed. It was shown that this method is useful for automatic evaluation of synthetic speech quality after major revisions of TTS systems, without the need for preparation and execution of time consuming and expensive subjective tests.
