The invention discloses a call voice information processing method and device, and the method comprises the steps: obtaining a microphone signal in a call process; processing the microphone signal to obtain signal feature information; and inputting the signal feature information into a call voice information processing model, and removing an echo signal and a noise signal in the microphone signal through the call voice information processing model to obtain a near-end signal in the microphone signal. According to the embodiment of the invention, the signal feature information is input into the model, the echo signal and the noise signal in the microphone signal can be removed only by using one model, and the near-end signal in the microphone signal is obtained. Therefore, compared with the prior art needing two models, the method can be realized through one model, and the two problems of echo cancellation and noise suppression are effectively solved while the calculation amount is reduced.
Description
technical field [0001] The present application belongs to the field of speech enhancement, and in particular relates to a method and device for processing call speech information. Background technique [0002] With the rapid development of communication technology in recent years, audio and video calls and online meetings have been rapidly popularized, and the quality of audio signal processing has become an important factor affecting the experience of audio and video calls. In the audio signal processing of audio and video calls or online conferences, noise reduction is the most critical factor that directly affects the quality of audio signals. Here, noise reduction mainly includes echo cancellation and noise suppression. [0003] At present, the existing schemes are mainly divided into three types: 1) Echo cancellation and noise suppression are performed through different signal processing algorithms; 2) Echo cancellation is performed through signal processing algorithms,...
