METHOD AND SYSTEM FOR OPERATION OF A VOICE ACTIVITY DETECTOR

摘要

The invention concerns a system (100) and method (400) for operation of a voice activity detector (230). The system can include a speaker (105), a first microphone (110) and a second microphone (120) in which the first microphone and the second microphone can capture acoustic output from the speaker. The system can also include an adaptive module (220) in which the first microphone and the second microphone can provide signals to the adaptive module, and the adaptive module can provide an input to the voice activity detector. The adaptive module can receive a first input (242) from the first microphone and a second input (243) from the second microphone and can attempt to determine (430) a transformation between the first and second inputs for setting a configuration of the voice activity detector.
