Abstract
The prosody of a speech signal is related to many factors: the social and geographical origin of the speaker, his or her emotional state, his physiological state (weariness, sickness, …) and the type of the sentence (interrogative, affirmative, etc.). A good synthesis or speech transformation system must account for all of these factors in order to produce a speech that sounds natural. In this paper, we propose a graphical interface for the modification of the prosodic features of the speech signal (the melodic curve - fundamental frequency and temporal
organization of the syllables - and the formantic trajectories) using the PSOLA algorithm. The interface allows the user to manually introduce the desired trajectories of the transformation parameters of the PSOLA algorithm in order to produce a transformed signal which has the desired prosody. The results are acceptable, especially for the modification of the fundamental frequency and of the temporal organization of the source signal.
Keywords
