Abstract
An entertainment system suitable for use in a vehicle and configured to control an output volume of the system includes a microphone and a processor. The microphone is configured to detect sound in a cabin of the vehicle, and output a microphone signal indicative of the sound. The processor is configured to determine a difference signal based on a difference between the microphone signal and an output signal corresponding to sound being output by the system, determine if the difference signal corresponds to human speech, and decrease the output volume of the system when the difference signal corresponds to human speech.
