A voice process apparatus and a method thereof capable of improving a receiving voice recognition ratio are provided to improve a recognition rate of received voice by adjusting the received voice by using a surrounding noise signal of a receiving side when receiving the voice signal from the receiving side during communication. A voice process apparatus capable of improving a receiving voice recognition ratio comprises an ADC(Analog to Digital Converter)(10,11), an equalizer(12,18), a wind noise canceller(13), an echo canceller(14), a noise canceller(15), a modem transmitter(16), a modem receiver(17), a volume/gain control unit(19), a spectrum adjusting unit(20), a DAC(Digital to Analogue Converter)(21), a microphone(M1, M2) and a speaker(SP1). The volume/gain control unit adjusts a gain and a volume of a received voice signal according to a level of a surrounding noise signal. The spectrum adjusting unit analyzes a frequency element with regard to the surrounding noise signal and adjusts the received voice signal inputted from the volume/gain control unit according to the analyzed result. |
