| Zusammenfassung: | The invention discloses a voice recognition device. The voice recognition device comprises at least one position acquisition device, a directional sound receiving device, a noise suppressor and a voice recognition processor. The position acquisition device is sequentially coupled to the directional sound receiving device, the noise suppressor and the speech recognition processor. The position acquisition device acquires an entity voice position of a sound source and outputs the voice position to the directional sound receiving device, so that the directional sound receiving device receives a voice signal generated by the sound source according to the voice position. The noise suppressor eliminates noise of the voice signal according to a noise model corresponding to the voice position so as to generate a voice recognition signal. The voice recognition processor receives the voice recognition signal and generates an operation signal according to the voice recognition signal. Therefore, the accuracy of voice re |
