Abstract

Examples of systems and methods described herein may receive audio signals from at least one microphone. Example systems and methods may generate noise cancellation signals based at least in part on the audio signals and extract target signals based at least in part on the audio signals using digital neural network processing. Example systems and methods may provide the noise cancellation signals and the target signals from at least one speaker.
