Abstract
Systems and methods for detecting a state of at least one button are disclosed herein. The method detects a first signal of a headset of a user. The first signal is indicative of the headset being coupled to a device. The headset has a microphone and at least one button. The method determines, based on the detected first headset signal, a first voltage of the microphone, and sets, based on the first voltage of the microphone, a threshold voltage for detecting a state of the at least one button. The method stores the threshold voltage and determines a second voltage of the microphone. The method compares the second voltage of the microphone and the stored threshold voltage, and generates, based on the comparison, a signal indicative of a state of the at least one button.
