چکیده
Development of a microprocessor-based speech recognition system for a low cost remotely operated underwater vehicle (ROV) is reported in this paper. The system is designed to enhance the operator-controls for the TITAN range of ROV's. The experimental system is developed on a Motorola evaluation board with a M68HC16 Hl-bit microcontroller. Recognition is based on the minimum Euclidean distance batween the energy functions of sampled templates. The algorithm is further enhanced with the incorporation of linear predictive coding and ceps!rai coefficients for distance measurement. It is implemented am:! tested on a PC-486 system with a Sour~Siaster card. Experimental resu!ts indicated that the speech= based system will simplify the operator control console but perfonnance of the HCH! microcontroller may not ba desirable when all the tasks of control, communication am:! speech recognition are taking place. Further resaarch is continued to improve the algorithms and system hardware so as to achieve acceptable aCC~Jracy am:! efficiency.
