Abstract


It is proposed to use developed digital speech signal compression algorithm based on wavelet transform in the unmanned aerial vehicle voice control system. It is implemented the estimation of compression data ratio and bit rate depending on the parameters of the correlation coefficient, the signal / noise ratio, peak signal / noise ratio and root-mean square error, which is the main criterion of performance of speech quality. The results of experimental studies suggest the feasibility of further practical application of the proposed digital speech signal compression algorithm based on wavelet transform in voice control systems unmanned aerial vehicle.
