    Abstract: The electronic device (1) is integrated in a chip (50) of semiconductor material, and comprises a control unit (3), a signal-conversion unit (4), and a non-volatile memory unit (5), which are connected together via a main transmission line (6). The signal-conversion unit (4) is designed to receive at input an analog signal correlated to a voice signal, and to generate at output a stream of appropriately compressed digital signals. The stream of compressed digital signals is then stored in pre-set memory locations of the non-volatile memory unit (5) according to the control signals generated by the control unit (3). During reproduction, the compressed digital signals stored in the non-volatile memory unit (5) are supplied to the signal-conversion unit (4), which decompresses them and sends them to a loudspeaker (43).
