METHOD FOR IMPROVING A SPEECH SIGNAL WITH A LOW DELAY, A COMPUTING DEVICE AND A COMPUTER-READABLE MEDIUM THAT IMPLEMENTS THE ABOVE METHOD Russian patent published in 2023 - IPC G10L21/02 G10L15/16 G06N3/02 

FIELD: computer technology.

SUBSTANCE: processing a speech signal with low delay. The method for improving a speech signal comprises obtaining a noisy waveform and sequentially processing blocks of samples of the noisy waveform using a speech signal improvement model to predict the corresponding blocks of samples of the denoised waveform. During this sequential processing of each block of noisy waveform samples, a speech signal improvement model is autoregressively determined by a block of previous denoised waveform samples, wherein this block of previous denoised waveform samples is predicted by the speech signal improvement model earlier in this sequential processing of the block of previous noisy waveform samples. The speech enhancement model is trained in TFM in conjunction with IAC.

EFFECT: increasing the accuracy of processing a speech signal with a low delay.
