ABSTRACT:
In accordance with one aspect of the dynamic volume control, an indication that a user desires to input oral data to a system through one or more microphones of the system is received. In response to receipt of the indication, a volume level for audible signals output by one or more speakers of the system is automatically adjusted. In accordance with another aspect of the dynamic volume control, an indication that a communications source is about to output data through one or more speakers of a system is received. In response to receipt of the indication, a volume level for audible signals output by the one or more speakers is automatically adjusted based at least in part on a current volume setting. The volume level for the audible signals can be determined based on one or more of a variety of different parameters.
