1. A system comprising:

  • an audio input module;

    an audio detection module in communication with the audio input module;

    a speech detection module in communication with the audio detection module;

    a wakeword recognition module in communication with the speech detection module; and

    a network interface module in communication with the wakeword recognition module,wherein;

    the audio detection module is configured to;

    receive audio input from the audio input module;

    determine a volume of at least a portion of the audio input;

    cause the audio input module to increase a sampling rate of the audio input based at least in part on the volume exceeding a threshold; and

    cause activation of the speech detection module based at least in part on the volume exceeding the threshold;

    the speech detection module is configured to determine a first score indicating a likelihood that the audio input comprises speech and cause activation of the wakeword recognition module based at least on part on the score; and

    the wakeword recognition module is configured to;

    determine a second score indicating a likelihood that the audio input comprises a wakeword; and

    cause activation of a network interface module based on the second score by providing power to the network interface module; and

    the network interface module is configured to transmit at least a portion of the obtained audio input to a remote computing device.
