Problems solved by technology

At present, the voice conversion method in the related art requires the user to record voice clips in advance, and perform model training and update according to the user's voice clips, and then perform voice conversion according to the updated model. This method has high requirements for the user's voice recording. The model needs to be updated before each voice conversion, the waiting time for voice conversion is long, and the flexibility is poor

Abstract

The invention discloses a voice conversion method and a device and electronic equipment, and relates to the technical field of voice conversion, voice interaction, natural language processing and deeplearning. According to the specific implementation scheme, the method comprises the followings steps: acquiring source voice of a first user and reference voice of a second user; extracting first voice content information and a first acoustic feature from the source voice; extracting a second acoustic feature from the reference voice; inputting the first voice content information, the first acoustic feature and the second acoustic feature into a pre-trained voice conversion model to obtain a reconstructed third acoustic feature, and obtaining the pre-trained voice conversion model according to voice training of a third user; and synthesizing the target speech according to the third acoustic feature. According to the method, the first voice content information and the first acoustic feature of the source voice and the second acoustic feature of the reference voice are input into the pre-trained voice conversion model, and the target voice is obtained and synthesized according to the reconstructed third acoustic feature, so that the waiting time of voice conversion can be shortened.

Description

technical field [0001] The present application relates to the technical fields of voice conversion, voice interaction, natural language processing, and deep learning in the field of computer technology, and in particular to a voice conversion method, device, electronic equipment and storage medium. Background technique [0002] The voice conversion method can convert a piece of voice of a user into a piece of voice with the timbre of the target user, so as to realize the imitation of the timbre of the target user. At present, the voice conversion method in the related art requires the user to record voice clips in advance, and perform model training and update according to the user's voice clips, and then perform voice conversion according to the updated model. This method has high requirements for the user's voice recording. The model needs to be updated before each speech conversion, and the waiting time for speech conversion is long and the flexibility is poor. Contents...
