Abstract
Dynamic Time Warping (DTW) is the most widely used algorithm for finite passwords or isolated words recognition system. However, the recognition rate using DTW is strongly influenced by the precision of voice activity detection(VAD), and the traditional DTW algorithm has more path to search when compared with the improved DTW algorithm will cost more time. To solve the problem, a novel recognition method for limited passwords using a new VAD algorithm of improved short-time Teager energy with double dynamic thresholds combined with the improved DTW algorithm for limited passwords or isolated words recognition is proposed in this paper. Experiment results show that the proposed method has better noise robustness and recognition rate than the short-time energy and zero-crossing rate with DTW or the improved DTW algorithm. Because of using the improved DTW, it is also real-time.
