Keyword spotting systems can be divided into two main groups: HMM-based and discriminative-based systems. Some of these systems apply a phonetic search algorithm to the sequence of recognized phones to find position of target keyword in a set of speech utterances. Thus, they need a fast and accurate phonetic search algorithm to find the position of the target keyword. In this paper, we propose a hierarchical search algorithm. In each level of hierarchy, some segments of input speech will be… CONTINUE READING
