We proposed a new expression of speech feature called orientation patterns which keeps its ability of detection higher in averaging of time domain. Because of this, we achieved to reduce number of frames in reference and input pattern in DP matching algorithm, then the calculation load were reduced. We constructed long term speech retrieval system by using this new expression. This system has RIFCDP as base matching algorithm which was already proposed. RIFCDP is an algorithm for spotting similar intervals between arbitrary reference pattern and arbitrary input pattern sequence synchronously with input frames.
