Popis:	In this paper, we present an algorithm for voice speed changing and pitch shifting based on TD-PSOLA. MATLAB simulation results indicate this algorithm can effectively improve the precision of pitch detection and convert speech into desired one. After the algorithm being realized and optimized, a real-time system is implemented on DSP, which can produce desired fundamental frequency and duration.
