Zusammenfassung:	Aspects of the subject technology provide for identifying a portion of one or more audio signals from one or more microphones of an electronic device that correspond to a sound-generating component of the electronic device. The identification of the portion of the audio signals may be based on a near-field impulse response for the sound-generating component and the one or more microphones. The electronic device may then be operated based on the audio signals and the identified portion of the audio signals. The sound-generating component may be a speaker, and operating the electronic device based on the audio signals and the identified portion of the audio signals may include performing a residual echo suppression by removing the identified portion of the audio signals from the audio signals, and transmitting, storing, and/or otherwise processing the residual echo suppressed audio signals.
