Abstract

ABSTRACT There are several systems like a wearable computer which can be controlled by Voice through the microphone. These systems often include the internal DSP (Digital Signal Processor) which recognizes and dictates the Voice. When the system states in SLEEP/Suspend mode or Power OFF/Hibernation mode, in order to recognize the Voice command for 'Wake up' or 'Power On', the DSP have to observe the Voice and keep on being powered at all times. As the DSP is always powered on, the battery is consumed and will be exhausted at last.
