Abstract
The present disclosure illustrates a voice apparatus and a dual-microphone voice system with noise cancellation. A voice detector and a noise detector simultaneously receive a first voice source and a second voice source to acquire a first main signal with a voice band and a second main signal with a burst noise band respectively. A voice filter filters a voice signal of the first main signal to remain a burst noise signal with a little voice signal (i.e., a remained noise). A noise filter filters a burst noise signal of the second main signal to remain a voice signal with a little burst noise signal (i.e., a remained voice). A post-filter generates a noise reduction gain according to the remained voice and the remained noise and adjusts the remained voice according to the noise reduction gain to generate the voice signal.
