    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.

    摘要: An earpiece (100) and a method (640) for acoustic management of multiple microphones is provided. The method can include capturing an ambient acoustic signal from an Ambient Sound Microphone (ASM) to produce an electronic ambient signal, capturing in an ear canal an internal sound from an Ear Canal Microphone (ECM) to produce an electronic internal signal, measuring a background noise signal, and mixing the electronic ambient signal with the electronic internal signal in a ratio dependent on the background noise signal to produce a mixed signal. The mixing can adjust an internal gain of the electronic internal signal and an external gain of the electronic ambient signal based on the background noise characteristics. The mixing can account for an acoustic attenuation level and an audio content level of the earpiece. Other embodiments are provided.
