Abstract
Described herein is an audio device with a microphone which may adapt the audio output volume of a speaker by either increasing or decreasing output volume based on an audio input volume from a user and a distance from the user to the audio device. The audio device may also adapt its output volume to lower the audio output based on detecting one or more interruptions including occupancy and acoustic sounds.
Claims27
A device comprising:
- a control circuit configured to:
- receive an acoustic input;
- detect a verbal request in the acoustic input;
- measure a received-request volume of the verbal request at the device;
- determine a distance between the device and a source of the verbal request;
- calculate a volume level of the verbal request at the source based on the received-request volume and the distance between the device and the source of the verbal request;
- determine the volume level of the verbal request at the source relative to a quiet threshold;
- determine a response volume level for a verbal response to the verbal request, wherein the response volume level is below the quiet threshold when the verbal request at the source is below the quiet threshold;
- and
- transmit audio output comprising the verbal response to the verbal request at the response volume level.
