摘要：
In accordance with an embodiment of the present invention, a noise reduction method for speech processing includes detecting if two signals from two microphones are so close to each other in non voice area that the two microphones are equivalent to Single-Microphone for noise/interference reduction processing. Single-Microphone noise/interference reduction processing algorithm is selected if the equivalent Single-Microphone is detected; Multiple-Microphone noise/interference reduction processing algorithm is selected if the equivalent Single-Microphone is not detected.
