Abstract

The invention discloses a timbre conversion method and device and electronic equipment, and belongs to the technical field of audio processing. The method comprises the following steps: carrying out feature extraction processing on received target voice information to obtain input spectrum parameters; determining first voice text parameters based on the input spectrum parameters; performing variational self-encoding processing on the input spectrum parameters based on a tone conversion model, and determining voice parameters; processing the first voice text parameters and the voice sound parameters based on the tone conversion model, and determining output spectrum parameters; and determining target voice information after tone conversion based on the output spectrum parameters. According to the embodiment of the invention, by determining the voice sound parameters, false recognition of tone conversion based on the output spectrum parameters determined by the first voice text parameters is reduced, error correction and fault tolerance of false recognition are realized, the conversion effect of tone conversion is ensured, and the reliability of tone conversion is improved.

Description

technical field [0001] The present application belongs to the technical field of audio processing, and in particular relates to a tone color conversion method, device and electronic equipment. Background technique [0002] Along with the continuous development of the field of audio processing technology, timbre conversion as a branch of the field of audio processing technology has also been developed rapidly. Voice conversion refers to converting the timbre of a person's voice while keeping the voice content unchanged. [0003] At present, the traditional timbre conversion scheme is a conforming system scheme based on the posterior probability of speech recognition factors, that is, through the introduction of speech recognition, "any-to-one" flexible conversion and high natural pronunciation effect are realized. Therefore, the conversion effect depends on the accuracy of speech recognition. As the feature extractor of the conversion model in the timbre conversion scheme, s...
