1. An electronic device, comprising:
an imager capturing one or more images of a subject engaging the electronic device;
an audio input receiving acoustic signals having audible frequencies from the mouth of the subject engaging the electronic device; and
one or more processors determining from the one or more images of the subject whether the mouth of the subject is oriented on-axis relative to the audio input or off-axis relative to the audio input;
the one or more processors adjusting a gain of the audio input associated with a subset of the audible frequencies when the mouth of the subject is oriented off-axis relative to the audio input, but only when the mouth of the subject is oriented off-axis relative to the audio input by at least a predefined rotation threshold defined by boundaries of the electronic device, such that the gain remains unadjusted until the mouth of the subject is oriented off-axis beyond the boundaries of the electronic device.
