本文提出了一种新的帧同步算法，通过比较参考模式序列中的任意间隔与输入模式序列中的任意间隔来发现相似间隔。实验结果表明，该算法能够有效地检测出参考模式与输入模式之间的相似间隔。我们已经应用该算法从语音数据库中的语音检索，并显示了实时语音/文本检索的可能性。所提出的算法可以提供广泛的应用，如通过检查输入数据的重复（相同的单词发音）的连续语音的摘要，和移动的机器人的位置识别。
This paper proposes a new frame-synchronous algorithm for spotting similar intervals by comparing arbitrary intervals in a reference pattern sequence with arbitrary intervals in an input pattern sequence. The algorithm is called Reference Interval-Free Continuous DP (RIFCDP) and the experimental results show that RIFCDP is successful in detecting the similar intervals between a reference pattern and an input. We have applied this algorithm to speech retrieval from a speech database and showed the possibility of real-time speech/text retrieval. The proposed algorithm can offer a wide range of applications such as digesting of continuous speech by checking the duplication of input data (same word utterance), and location identification of a mobile robot.
