Abstract

The embodiment of the present invention discloses a speech processing method and device, a storage medium, and electronic equipment. The speech processing method includes the steps: acquiring originalvoice, inputting the original voice into a generative sub-model of a pre-trained GAN (Generative Adversarial Network) model if the original voice is reverberation voice, wherein the generative submodel is used to perform dereverberation processing of the original voice, and the output voice of the generative submodel is determined as dereverberation voice. By adopting the above scheme, the methodachieves the dereverberation of the original voice input by the user based on the GAN, and the voice features of the original voice do not need to be extracted, so the method quickly obtains the high-precision dereverberation voice, thereby improving the processing efficiency and processing precision of the original voice signal.

Description

technical field [0001] The embodiments of the present application relate to the technical field of voice processing, and in particular, to a voice processing method, device, storage medium, and electronic equipment. Background technique [0002] With the rapid development of electronic devices such as mobile phones and robots, more and more voice functions are applied to electronic devices, such as voiceprint unlocking and voiceprint wake-up. [0003] However, when the user is far away from the electronic device, the voice signal collected by the microphone of the electronic device has reverberation, which reduces the clarity of the collected voice signal and affects the recognition rate of voiceprint information. At present, the commonly used reverberation technology is WRE (weighted prediction error, weighted prediction error) technology. In the frequency domain, the reverberation component is estimated for the first few frames of the reverberation speech, and the reverber...
