Abstract(in English) | We have proposed a spoken term detection (STD) method using a suffix array, and have evaluated its search speed on a large speech database. This method employs iterative lengthening search and keyword division for quicker search, as well as utilizing the suffix array as a data structure. In this method, we control the threshold value to keep the search results unchanged when searching for the divided keywords. However, we have only considered the cases where the original keyword is equally divided. In this paper, we investigate theoretical conditions to be satisfied by the threshold values when the keyword is divided into arbitrary length and number of sub-keywords. |
