This paper presents several experimental results on the study of the factors that affect the prosody in Romanian in order to create the basis of a computational model for prosody description in a system for Text To Speech (TTS) synthesis. Different manifestation levels of prosodic phenomena together with their importance for TTS are presented. The experiments reported here, mainly take into consideration the linguistic aspect of prosody in a qualitative and quantitative manner: the influence of the accent at word and sentence level, the intonation, the rhythm and the speech rate. The evaluated parameters are: fundamental frequency, the intensity and the duration. Such parameters are going to be predicted as well as possible by a linguistic computational model which will be developed in the future.
