[Problem] To provide a voice recognition system and a voice recognition device with which reduction in recognition time in voice data transmitted by wireless communication is achieved. [Solution] A voice recognition system 100 uses wireless communication W, and is provided with an acquisition means, a transmission means, a reception means, and a recognition means. The acquisition means acquires voice data on the basis of voice. The transmission means transmits the voice data by wireless communication using a UHF band. The reception means receives the voice data as a continuous signal at a time. The recognition means derives a recognition result obtained by recognizing the content of the voice data using phoneme recognition. For example, the transmission means transmits the voice data on which packetization processing is not performed.
