Abstract

"This paper proposes a method to prosodic speech modification based on residual-excited linear predictive coding (RELP) applied to speech synthesis. In this way, pitch and time scale modifications are carried out requiring a very low computational complexity. Formal subjective test comparing the proposed approach with TD-PSOLA, under conditions of increasing and decreasing the pitch, are achieved. For all tested cases, the obtained results show a better performance of the proposed approach as compared with TD-PSOLA."
