Discriminant Analysis of Voice Commands in the Presence of an Unmanned Aerial Vehicle

The aim of this study was to perform discriminant analysis voice commands in the presence an unmanned aerial vehicle equipped with four rotating propellers, as well obtain background sound levels and speech intelligibility. measurements were taken laboratory conditions absence vehicle. Discriminant (left, right, up, down, forward, backward, start, stop) performed based on mel-frequency cepstral coefficients. Ten male speakers took part experiment. hovered at a height 1.8 m during recordings distance 2 from speaker 0.3 above measuring equipment. coefficients showed promising classification equal 76.2% for speakers. Evaluated intelligibility obtained did not exclude verbal communication
