Implementation of the Arabic Speech Synthesis with TD-PSOLA Modifier

This research describes techniques to improve the precision of prosodic modifications in the Arabic speech synthesis, using the TD-PSOLA (Time Domain Pitch Synchronous Overlap-Add) method. This approach is based on the decomposition of the signal into overlapping frames synchronized with the pitch period. The main objective is to preserve the consistency and accuracy of the pitch marks after prosodic modifications of the speech signal.
