Abstract

The invention relates to a voice conversion method and device, electronic equipment and a storage medium, and the method comprises the steps: extracting the rhythm of a target voice, and obtaining a target rhythm parameter, the target voice being a voice needing voice conversion; inputting the target voice into an end-to-end voice recognition encoder to obtain a content vector output after the end-to-end voice recognition encoder processes the target voice; and performing voice conversion on the target voice according to the target rhythm parameter and the content vector, and because the time resolution of the content vector is consistent with the time resolution of the target voice, making the phoneme feature represented by the content vector consistent with the phoneme feature contained in the target voice, so that the content vector can completely reflect the details of the target voice, and the accuracy of voice conversion is improved. The voice conversion effect is improved, the phoneme features included in the content vector are not classified, the problem that phoneme classification is inaccurate and voice conversion is affected is avoided, and the voice conversion effect is further improved.

Description

technical field [0001] The present application relates to the field of voice conversion, 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 speaker's personality characteristics, so that the timbre of the target voice sounds like the target speaker's timbre, while the semantics do not change; at present, voice conversion technology is easy to lose the target Voice detail content information, resulting in poor voice conversion effect. Contents of the invention [0003] The present application provides a voice conversion method, device, electronic equipment and storage medium to solve the problem in the related art that the detailed content information...
