K. Drosos, M. O. Heikkinen, S. Vesa, and M. T. Vilermo, “Speech and noise disentanglement for acoustic echo cancellation,” U.S. Patent US20260080885A1, filed Aug. 27 , 2025; published Mar. 19, 2026
The present disclosure relates to an apparatus, that obtains a far-end signal and a near-end microphone signal, determines, based on at least the far-end signal, a far-end speech signal estimate and a far-end noise signal estimate, determines, based on at least the near-end microphone signal, a near-end microphone speech signal estimate and a near-end microphone noise signal estimate, determines, based on at least the far-end speech signal estimate and the near-end microphone speech signal estimate, a predicted near-end speech signal, determines, based on at least the far-end noise signal estimate and the near-end microphone noise signal estimate, a predicted near-end noise signal and outputs at least the predicted near-end speech signal and predicted near-end noise signal.
