Currently, unmanned aerial vehicles, such as drones, are becoming a part of our lives and extend to many areas of society, including the industrialized world. A common alternative for controlling the movements and actions of the drone is through unwired tactile interfaces, for which different remote control devices are used. However, control through such devices is not a natural, human-like communication interface, which sometimes is difficult to master for some users. In this research, we experimented with a domain-based speech recognition architecture to effectively control an unmanned aerial vehicle such as a drone. The drone control was performed in a more natural, human-like way to communicate the instructions. Moreover, we implemented an algorithm for command interpretation using both Spanish and English languages, as well as to control the movements of the drone in a simulated domestic environment. We conducted experiments involving participants giving voice commands to the drone in both languages in order to compare the effectiveness of each, considering the mother tongue of the participants in the experiment. Additionally, different levels of distortion were applied to the voice commands to test the proposed approach when it encountered noisy input signals. The results obtained showed that the unmanned aerial vehicle was capable of interpreting user voice instructions. Speech-to-action recognition improved for both languages with phoneme matching in comparison to only using the cloud-based algorithm without domain-based instructions. Using raw audio inputs, the cloud-based approach achieves 74.81% and 97.04% accuracy for English and Spanish instructions, respectively. However, with our phoneme matching approach the results are improved, yielding 93.33% accuracy for English and 100.00% accuracy for Spanish.

<p class="Default">Unmanned Aerial Vehicles have gained well known attention in recent years for a numerous applications such as military, civilian surveillance operations as well as search and rescue missions. The UAVs are not controlled by professional pilots and users have less aviation experience. Therefore it seems to be purposeful to simplify the process of aircraft controlling. The objective is to design, fabricate and implement an unmanned aerial vehicle which is controlled by means of voice recognition. In the proposed system, voice commands are given to the quadcopter to control it autonomously. This system is navigated by the voice input. The control system responds to the voice input by voice recognition process and corresponding algorithms make the motors to run at specified speeds which controls the direction of the quadcopter.</p>

This paper studies the 3D flocking control problem for unmanned aerial vehicle swarm when tracking a desired trajectory. In order to allow the unmanned aerial vehicle swarm to form the stable flocking geometry on a same horizontal plane, the altitude consensus algorithm is applied to the unmanned aerial vehicle altitude control channel, using the trajectory altitude as the external input signals. The flocking control algorithm is only performed in the horizontal channel to control the horizontal position of unmanned aerial vehicles. The distributed tracking algorithm, which controls the local averages of position and velocity of each unmanned aerial vehicle, is implemented to achieve the better tracking performance. The improved artificial potential field method is introduced to achieve the smooth trajectory when avoiding obstacles. The practical dynamic and constraints of unmanned aerial vehicles are also taken into account. Numerical simulations are performed to test the performance of the proposed control algorithm.

The article proposes and investigates the system of protected voice radio control by the functions of an unmanned aerial vehicle, which is based on the first developed method of secure transmission of voice commands of radio control and the idea of voice authentication of legal subjects of management, where only the voice radio channel is used to transmit control information, thereby allowing the system to be implemented in existing voice radio systems, where on the betraying side is the subject of control, and as a receiver an unmanned aerial vehicle that performs the spoken voice commands. The proposed idea makes it possible to significantly complicate the struggle of malefactors with this kind of systems, since the frequencies at which the voice mobile radio is operating are in common use, and means fighting with this kind of systems will result in the failure of public voice mobile communications. The system of protected voice control of an unmanned aerial vehicle makes it possible to ensure sufficient confidentiality of the transmitted voice commands from the interception of information with the purpose of illegally capturing or destroying an unmanned aerial vehicle throughout the flight. For the first time, the method of voice authentication of legal subjects of management based on the idea of successive substitution of the authentication parameters of the control subject for each subsequent voice command on the authentication parameters from the database, the sequence of which was performed before the flight in a pseudorandom manner and synchronized. The expediency of using the presented system of protected voice radio control functions of an unmanned aerial vehicle is substantiated and experimentally proved. The results of automatic recognition of voice control commands are evaluated using a classifier constructed using the minimum distance criterion, where the decision on the positive identification of voice commands is made by the criterion of a minimum variance in a given threshold of acceptable recognition. The obtained results of experimental research allow to draw a conclusion about the expediency of further practical application of the presented system of protected voice radio control by the functions of an unmanned aerial vehicle
