TELEPHONE CALL RECORDING DEVICE AND TELEPHONE CALL RECORDING RETRIEVAL METHOD

PROBLEM TO BE SOLVED: To enable target telephone call recording information to be quickly retrieved in a telephone recording device. SOLUTION: Telephone call information is recorded in a recording file storage 127. A voice processor 121 detects information on a group of PB signals from telephone call information. A phoneme exchange/comparison section 123 detects predetermined voice information from the telephone call information. A data storage 130 for retrieval allows the detected information on the group of PB signals to correspond to the recording region information of the telephone call information recorded in a recording file storage 127 for retention, immediately before the voice information when the voice information is detected. A retrieval processor 128 receives key information for retrieval, detects the information on the group of PB signals that coincides with the key information, follows read information corresponding to the detected information of the group of PB signals, and outputs the telephone call information recorded in the recording file storage 127.
