The wake-word detector components 554 are configured to monitor and analyze received audio to determine if any wake words are present in the audio. The wake-word detector components 554 may analyze the received audio using a wake word detection algorithm. If the wake-word detector 554 detects a wake word, a network microphone device may process voice input contained in the received audio. Example wake word detection algorithms accept audio as input and provide an indication of whether a wake word is present in the audio. Many first- and third-party wake word detection algorithms are known and commercially available. For instance, operators of a voice service may make their algorithm available for use in third-party devices. An algorithm may be trained to detect certain wake words.
In some embodiments, a network microphone device may include additional and/or alternate components for detecting and facilitating capture of voice input. For example, a network microphone device may incorporate linear filtering components (e.g., in lieu of beam former components), such as components described in U.S. patent application Ser. No. 15/984,073, filed May 18, 2018, titled “Linear Filtering for Noise-Suppressed Speech Detection,” which is incorporated by reference herein in its entirety.
