1. A playback device comprising:

  • a top face;

    a bottom face opposite the top face, wherein the bottom face comprises a longest face of the playback device;

    a side face perpendicular to the top face and the bottom face;

    a set of microphones comprising;

    a first subset of one or more microphones positioned along the top face; and

    a second subset of one or more microphones positioned along the side face;

    an orientation sensor;

    one or more processors; and

    tangible, non-transitory computer-readable medium having stored thereon instructions executable by the one or more processors to cause the playback device to perform functions comprising;

    determining that the playback device is in a horizontal orientation based on an indication from the orientation sensor that a longest face of the playback device is substantially parallel to a surface on which the playback device is positioned, wherein, in the horizontal orientation, the bottom face is substantially parallel to the surface and the side face is substantially perpendicular to the surface;

    selecting the first subset of one or more microphones instead of the second subset of one or more microphones for sound input detection based on the determination that the playback device is in the horizontal orientation;

    detecting, via the first subset of one or more microphones, a sound input;

    processing the sound input detected via the first subset of one or more microphones; and

    based on the sound input, executing one or more commands.
