Present invention is a voice recording and playback apparatus with random and sequential addressing, comprising: a processor for all information operation of the apparatus; a record/playback unit for receiving outside sounds and replaying the sounds; a storage unit for storing the outside sound data received by the record/playback unit; an output unit for assigning the outside sound data with a serial number (S/N) and outputting into an S/N bar code; a sensor for sensing the S/N bar code or a Radio Frequency Identification (RFID) and picking up the sound data for the S/N or RFID and replaying the sound data by the record/playback unit; and a power supplier for the apparatus. Accordingly, after the sensor senses the S/N bar code or the RFID, the sound data for the S/N or RFID can be found in a random addressing style to rapidly find the sound data stored in the storage unit.
