Abstract
A voice recognition device includes at least one position retrieving device, a directional voice receiving device, a noise suppressor, and a voice recognition processor. The position retrieving device is sequentially coupled to the directional voice receiving device, the noise suppressor, and the voice recognition processor. The position retrieving device retrieves the physical voice position of a voice source and outputs the voice position to the directional voice receiving device. The directional voice receiving device receives a voice signal generated by the voice source according to the voice position. The noise suppressor eliminates the noise of the voice signal to generate a voice recognition signal based on noise model corresponding to the voice position. The voice recognition processor receives the voice recognition signal and generates an operating signal based on the voice recognition signal.
