Abstract

The invention relates to a voice conversion method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the content extraction of a to-be-converted voice, and obtaining a target feature; encoding the target feature to convert the target feature into a target vector; target rhythm parameters corresponding to the to-be-converted voice are obtained, the target vector is decoded on a target tone according to the target rhythm parameters, the Mel-Per features of the target tone are obtained, and the target rhythm parameters do not contain the tone of the to-be-converted voice; by removing the timbre of the to-be-converted voice contained in the target rhythm parameter, the problem that the timbre of the original speaker is leaked into the converted voice due to the fact that the feature of the to-be-converted voice is directly used for generating the Mel-Per feature, and thus the effect timbre after voice conversion is different from the timbre of the target speaker is solved; therefore, the to-be-converted voice is closer to the target tone after being converted, and the voice conversion effect is improved.

Description

technical field [0001] The present application relates to the technical field of voice processing, and in particular to a voice conversion method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of deep learning technology, neural network-based voice conversion (Voice Conversion, VC) technology is also becoming more and more mature. Speech conversion refers to changing the acoustic feature parameters related to the personality characteristics of the source speaker to make it sound like the voice of the target speaker without changing the semantics, that is, to remove the timbre of the original speaker. . In the related technology, in the voice conversion technology, the mel spectrum feature is directly generated according to the prosody parameters of the voice to be converted, so as to improve the expressiveness of the model. Therefore, there is a big defect in the related technology. , the obtained speech cont...
