Abstract Systems and methods for determining and adapting to changes in microphone performance of playback devices are disclosed herein. In one example, an audio input is received at an array of individual microphones of a network microphone device. Output microphone signals are generated from each of the individual microphones based on the audio input. The output microphone signals are analyzed to detect a trigger event. After detecting the trigger event, the output microphone signals are compared to detect aberrant behavior of one or more of the microphones. Optionally, corrective actions can be taken or suggested based on the detection of aberrant behavior of one or more microphones. L'invention concerne des systèmes et des procédés de détermination et d'adaptation à des changements de performance de microphone de dispositifs de lecture. Dans un exemple, une entrée audio est reçue au niveau d'un réseau de microphones individuels d'un dispositif de microphone de réseau. Des signaux de microphone de sortie sont générés à partir de chacun des microphones individuels sur la base de l'entrée audio. Les signaux de microphone de sortie sont analysés afin de détecter un événement déclencheur. Après détection de l'événement déclencheur, les signaux de microphone de sortie sont comparés afin de détecter un comportement aberrant d'un ou plusieurs des microphones. Éventuellement, des actions correctives peuvent être prises ou suggérées sur la base de la détection d'un comportement aberrant d'un ou plusieurs microphones.
