1. A voice activity detection apparatus comprising:
- a capacitive sensor providing a capacitive sensor output signal, wherein the capacitive sensor detects whether the capacitive sensor is in contact with a user skin;
a voice activity detector sensor providing a voice activity detector sensor output signal, wherein the voice activity detector sensor detects vibration of human tissue associated with user speech; and
a processor which receives the capacitive sensor output signal and the voice activity detector sensor output signal, wherein the voice activity detector sensor output signal is processed to determine a voice activity status only if the capacitive sensor output signal indicates that the capacitive sensor is in contact with the user skin.

Abstract
A voice activity detection apparatus having a capacitive sensor and a voice activity detector sensor. The voice activity detector sensor detects vibration of human tissue associated with user speech. Utilization of the voice activity detector sensor output is tied to the output of the capacitive sensor, where the capacitive sensor detects whether it is in contact with user skin.
