A voice recognition system and method are provided. The voice recognition system comprises: a microphone array (101), an audio coding circuit (102), a Bluetooth transmission module (202), a Bluetooth receiving module (201), and a main control integrated circuit (205). The microphone array (101) is used to receive a voice signal, convert the voice signal into an analog audio signal, and output the analog audio signal to the audio coding circuit (102). The audio coding circuit (102) is used to convert the received analog audio signal into a digital audio signal, and output the digital audio signal to the main control integrated circuit (205). The Bluetooth transmission module (202) is used to receive the voice signal, convert the voice signal into a digital audio signal, and sent the digital audio signal to the Bluetooth receiving module (201) in a Bluetooth manner. The Bluetooth receiving module (201) is used to send the received digital audio signal to the main control integrated circuit (205). The main control integrated circuit (205) is used to select the digital audio signal from the audio coding circuit (102) or the digital audio signal from the Bluetooth receiving module (201) to perform recognition. The voice recognition system and method solve the problem of the incapability of a voice recognition system, with audio input being from only a microphone array, in recognizing a distance voice. |
