Original Abstract Submitted
this disclosure provides methods, devices, and systems for audio signal processing. the present implementations more specifically relate to speech enhancement techniques that are agnostic to varying signal levels in near-end audio signals. in some aspects, a speech enhancement system may include a delay estimator, an input normalizer, and an acoustic echo and noise (aen) decoupling filter. the delay estimator receives a near-end audio signal via a microphone and a far-end audio signal for output via a speaker and estimates a reference audio signal based on a delay between the near-end audio signal and the far-end audio signal. the input normalizer normalizes a loudness of the near-end audio signal and the reference audio signal. the aen decoupling filter determines a set of masks based on the normalized audio signals and suppresses an echo component and a noise component of the near-end audio signal based on the set of masks.
