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.
