Abstract
The present invention discloses a voice recognition system and method, wherein the voice recognition system comprises: a microphone array for receiving a voice signal, converting the voice signal into an analog audio signal, and outputting the analog audio signal to an audio coding circuit; the audio coding circuit for converting the received analog audio signal into a digital audio signal, and outputting the digital audio signal to a main control integrated circuit; a Bluetooth transmitting module for receiving a voice signal, converting the voice signal into a digital audio signal, and sending the digital audio signal to a Bluetooth receiving module via Bluetooth; the Bluetooth receiving module for sending the received digital audio signal to the main control integrated circuit; the main control integrated circuit for selecting the digital audio signal from the audio coding circuit or the digital audio signal from the Bluetooth receiving module to perform recognition. The technical solution of the present invention solve the problem of the incapability of a voice recognition system, with audio input being from only a microphone array, in recognizing a long-distance voice.
