摘 要:Support vector machine(SVM)has a good application prospect for speech recognition problems;still optimum parameter selection is a vital issue for *** improve the learning ability of SVM,a method for searching the optimal parameters based on integration of predator prey optimization(PPO)and Hooke-Jeeves method has been *** PPO technique,population consists of prey and predator *** prey particles search the optimum solution and predator always attacks the global best prey *** solution obtained by PPO is further improved by applying Hooke-Jeeves *** method is applied to recognize isolated words in a Hindi speech database and also to recognize words in a benchmark database TI-20 in clean and noisy environment.A recognition rate of 81.5%for Hindi database and 92.2%for TI-20 database has been achieved using proposed technique.
