Abstract
To reduce the risk of brown outs and resets in a mobile station using a far-field speaker, a voltage level of a battery and a level of an input audio signal are monitored. When the level of the audio signal increases past a threshold level, and the voltage level of the battery falls below a threshold voltage, an attenuation is determined and applied to the audio signal. The applied attenuation reduces the volume of the audio signal, which reduces the risk of a brown out or a reset due to insufficient voltage in the mobile station.
