摘要：
Voice conversion has become one current researching hotspot in speech signal processing. The article designs and establishes a voice conversion system based on Gaussian mixture model (GMM) and Artificial Neural Network (ANN) after researching the existing voice conversion algorithms. The core is to obtain respectively three mapping rules by training spectral envelope and its residual with GMM, and pitch contrail with BP network. And the voice is transformed according to the three mapping rules above. Finally, the algorithm simulation, the system implementation and algorithm performance evaluating of voice conversion is completed. The theoretic analysis and simulating results reveal that the algorithm and the system of voice conversion are effective.
