Abstract
⺠A set of features based on wavelet packets was optimized for speech recognition. ⺠A wrapper for feature selection was designed by means of a genetic algorithm. ⺠A non-orthogonal representation was obtained, which allowed to increase classification performance. ⺠The optimized features improved the classification results in noise conditions.
