An audio packet loss repairing method, device and system based on a neural network. The method comprises: obtaining an audio data packet (S), the audio data packet comprises a plurality of audio data frames, and the plurality of audio data frames at least comprise a plurality of voice signal frames; determining a position of a lost voice signal frame in the plurality of audio data packet to obtain position information of the lost frame (S), the position comprising a first preset position or a second reset position; selecting, according to the position information of the lost frame, a neural network model for repairing the lost frame (S), the neural network model comprising a first repairing model and a second repairing model; and sending the plurality of audio data frames to the selected neural network model so as to repair the lost voice signal frame (S).

Neural network-based audio packet loss restoration method and apparatus, and system

A speech noise reduction processing method, an apparatus, a computer device and a storage medium. The method comprises: responsive to a distance between a speech collection device and a target object being detected to reach a preset value, acquiring a noisy speech signal collected by the speech collection device and performing frequency division processing on the noisy speech signal to obtain a low-frequency band signal; acquiring an amplitude spectrum and a phase spectrum of the low-frequency band signal; acquiring a modulation domain signal corresponding to the amplitude spectrum; performing spectral subtraction to obtain a noise-reduced modulation domain amplitude spectrum; compensating the modulation domain phase spectrum to obtain the compensated modulation domain phase spectrum; and obtaining a noise-reduced low-frequency band signal based on the compensated modulation domain phase spectrum, the noise-reduced modulation domain amplitude spectrum and the phase spectrum of the low-frequency band signal.
