Abstract

The invention relates to the technical field of computers. The invention discloses a voice processing method and device, electronic equipment and a storage medium. and relates to artificial intelligence technology, voice classification is performed by using a machine learning technology in artificial intelligence, and the method comprises the steps of converting to-be-processed voice into a rhythmic embedded vector, decomposing the rhythmic embedded vector into a preset number of basic embedded GST, and obtaining a style embedded vector representing voice rhythm features according to the preset number of GST; and obtaining a classification result corresponding to the to-be-processed voice according to the style embedding vector. According to the voice processing method and device, the electronic equipment and the storage medium provided by the embodiment of the invention, the accuracy of voice classification can be improved, and the universality is better.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a voice processing method, device, electronic equipment and storage medium. Background technique [0002] The existing neural network-based speech classification methods usually perform short-time Fourier transform on the speech data, and then convert it into the corresponding spectrogram, and then extract a set of frequency domain information from the spectrogram based on the engineering characteristics of the audio. The collection is used as the speech feature vector input to the neural network, and then the classification result is obtained. Therefore, the existing speech classification methods require developers to have professional knowledge in audio to determine which information to extract from the spectrogram as speech feature vectors, and the method for extracting speech feature vectors is not universal. Contents of the invention [0003] Embodiments o...
