The natural tone synthesizer adds noise to impulse to produce natural vocal sound. The synthesizer includes an interfacing unit (9) for interfacing a keyboard with a digital signal processor (4) for receiving Hangul character data, a sound data ROM (7), a program ROM (8), an address decoder (8) for selecting the sound data ROM (7) or the program ROM (8) by decoding data selection signal (DS) and program selection signal (PS), a buffer (6) for buffering address signals (A0-A15) transmitted from a DSP to designate addresses of the ROMs (7,8), and a digital to analog converter (3) for converting digital sound signal transmitted from the DSP into analog signal. |
