Realization and design of a pilot assist decision-making system based on speech recognition
A system based on speech recognition is proposed for pilot assist
decision-making. It is based on a HIL aircraft simulation platform and uses the
microcontroller SPCE061A as the central processor to achieve better reliability
and higher cost-effect performance. Technologies of LPCC (linear predictive
cepstral coding) and DTW (Dynamic Time Warping) are applied for isolated-word
speech recognition to gain a smaller amount of calculation and a better
real-time performance. Besides, we adopt the PWM (Pulse Width Modulation)
regulation technology to effectively regulate each control surface by speech,
and thus to assist the pilot to make decisions. By trial and error, it is
proved that we have a satisfactory accuracy rate of speech recognition and
control effect. More importantly, our paper provides a creative idea for
intelligent human-computer interaction and applications of speech recognition
in the field of aviation control. Our system is also very easy to be extended
and applied.Comment: 10 pages, 8 figure
