PURPOSE: To save energy for a measuring work and measured data processing, by recording a measuring point and a measured value in a magnetic tape by a voice, recognizing them by a voice, and converting them to a data format which can be processed, in a marine use measured data processing device for processing a measured data.

CONSTITUTION: A measuring person carrying a tape recorder 12 and a microphone 13 executes a measurement at a measuring spot simultaneously with a sign. This measurement is recorded in a magnetic tape 11 by a voice in accordance with a format prescribed in advance. A voice recognizing device 14 reproduces the magnetic tape 11, recognizes the recorded measured data, and displays it on a digital display 15. Also, the measured data is processed by an electronic computer 16, and a result of processing is outputted to a printer 17 and is recorded. In this way, analysis and recording can be executed automatically, therefore, labor and time for the measuring work and the data processing are improved, and also they can be executed exactly.
