This paper uses FPGA speech recognition command as the four-rotor aerial remote control command．The FPGA can quickly process information combined voice control of the simple，accurate and flexible features． Thecontrol system is divided into two parts． The four-rotor craft uses the single-chip computer and it uses the fuzzyneural network PID to control the speed of the four-rotor propeller to achieve the control of the flying height anddirection of the fuselage． The voice remote command uses FPGA to optimize the hidden markov model thatcompletes the command control of the flight attitude of the fuselage． The simulation of the four-rotor control systemhas a strong real-time，and the system can control the four rotorcraft to complete the aerial mission better．
