The circuit includes a key board interfacing section (10) for interfacing input/output signals and key signals of an electronic key board (11). An analogue/digital and digital/analogue converter (1) converts user vocal signals to digital signals, and also converts linear prediction codes and synthesized data to analogue signals to supply the output signals through an amplifier to a speaker (3). A ditial signal processor (5) processes the output signals of the converter (1) to store the processed output in an audio data RAM (8), and synthesizes linear prediction data by reading the stored data of the RAM (8). |
