<p>This paper presents the design of a Micro Air Vehicle (MAV) operated by speech commands. A person from a base station can comfortably control the motion of the MAV by issuing speech commands. This system proposes to have two units, one in the base station which is the control unit and the other is a flying machine. The base station unit consists of a Digital Signal Processor (DSP) which performs a speaker dependent speech recognition algorithm for a predefined command library. The DSP generates control signals which are wirelessly transmitted to the MAV. A Field Programmable Gate Array (FPGA) is placed in the MAV for on-board operations. The FPGA receives the wirelessly transmitted control signals and alters the motion of the MAV based on the control signals received. The MAV consists of a single rotating wing with two rotors placed on either side of the fuselage, providing it with the capability of vertical take-off and landing (VTOL).</p>
