User sensing system and method for low power voice command activation in wireless communication systems

A voice controlled apparatus included in a wireless device, comprising:

• a plurality of sensors arranged on the device;
• a microphone;
• a controller to sample signals from at least one of the plurality of sensors;
• a processor coupled to the controller;
• and
• a voice activated detection (VAD) application running on the processor and coupled to the controller and the microphone.

A voice command control apparatus included in a device, comprising:

• means for sensing arranged on one or more surfaces of the device;
• means for detecting sound;
• means for controlling coupled to the sensing means for sampling signals from one or more of the plurality of sensing means;
• means for processing at least one of the sampled signals;
• and
• means for voice detection and interpretation.

A non-transitory computer readable media including instructions which when executed by a processor cause the processor to perform the following steps:

• sampling signals from a plurality of sensors on the device;
• determining if the device is in a hands-on state by a user on the basis of the signal sampling;
• and
• enabling a voice activated detection (VAD) application on the device on the basis of the determination.
