The present invention relates to a noise removal apparatus, a noise removal method, a voice recognition apparatus using the noise removal apparatus, and a vehicle equipped with the voice recognition apparatus. The noise removal apparatus may comprise: a gain acquisition unit for determining a gain and a correction value for the obtained gain by using a signal-to-noise ratio of an input signal; and a gain application unit for obtaining an output signal corresponding to the input signal by using the gain and the correction value, wherein the proportion, in the output signal, of input signals in which noise is removed and input signals in which noise is not removed can be determined in accordance with the correction value. The purpose of the present invention is to increase the voice recognition rate even in situations with a lot of noise. |
