End-to-end voice synthesis method and system based on DNN-HMM bimodal alignment network
ActiveCN111739508AImprove fault toleranceSimplify the alignment processSpeech recognitionNeural architecturesSynthesis methodsEngineering
The invention discloses an end-to-end voice synthesis method and system based on a DNN-HMM bimodal alignment network, and belongs to the field of intelligent voice interaction. According to the method, a frame length prediction module is used for replacing a traditional end-to-end attention autoregressive structure, and a convolutional change module and a bidirectional long-short-term memory network are used for constructing an encoder and a decoder, so that a large number of model parameters are reduced. On the basis that a phoneme frame length sequence is obtained through DNN-HMM bimodal alignment network training, an end-to-end voice synthesis model is trained, and thus the process that a traditional end-to-end voice synthesis model obtains text and audio alignment information in an autoregressive attention mode is avoided. The trained model not only can ensure the high naturalness of the audio synthesized by the end-to-end model, but also can greatly reduce the consumption of computing resources and the time proportion during voice synthesis, so that the end-to-end voice synthesis technology can be deployed on hardware with low computing resources.
