Abstract

The invention relates to a voice filtering method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the alignment operation of a rhythm vector of a target voice according to a voice alignment sequence, so as to obtain a plurality of groups of alignment vectors, and enabling the voice alignment sequence to be a sequence obtained by carrying out the phoneme division of the target voice; obtaining a hidden state of each group of alignment vectors, and carrying out downsampling on the hidden state to obtain a downsampling vector; and reconstructing the downsampling vector to obtain a filtering rhythm vector consistent with the rhythm vector in length, the filtering rhythm vector being used for performing voice conversion on the target voice. According to the method, the voice alignment sequence is introduced to align the rhythm vector, and meanwhile, hidden information carrying a plurality of vectors is used for reconstruction to obtain the filtered rhythm vector, so that the defect of selection for reconstruction by a random vector is overcome, and enough rhythm information is reserved while the rhythm vector of the target voice is filtered.

Description

technical field [0001] The present application relates to the technical field of voice conversion, and in particular to a voice filtering 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. However, there is an important defect in the current voice conversion technology , the expressive power of the original voice cannot be preserved, but the expressive power is particularly important in voice conversion technology. In the related technology, in the speech conversion technology, the mel spectrum of the original speech is directly used as a prosody module ...
