PURPOSE: To shorten the process time without requiring large memory capacity by detecting a target pattern from candidates obtained by setting a precedent- stage as candidate selection and a succeeding stage as high precision by DP arithmetic.
CONSTITUTION: A CPU 6 controls the DP arithmetic and the output of the result of a personal computer 11 through an input/output control system 10 in addition to control over an A/D converter 4 and the storage of data. When data is inputted from the A/D converter 4, precedent-stage DP arithmetic is performed first. Namely, the distance to standard data previously stored in a RAM 9 is found. A next candidate selecting process is performed after speech data of a specific time, e.g. of one word and all inputted and arithmetic corresponding to the data is all completed. The precedent-stage arithmetic is naturally not certain, so a selecting process for performing the DP arithmetic again is carried out for standard pattern data of a distance result entering a specific range.
