Abstract

PURPOSE: To make it possible to output sound signals for an artificial sound and a natural voice by a simple program by writing waveform data in a prescribed address of a storage means and allowing a sound signal to pass the storage means as it is. CONSTITUTION: When waveform data are transferred from a CPU through a transfer means, the data are successively stored in prescribed addresses specified by an address counter in the storage means. When the storage means storing the waveform data are accessed by prescribed address frequency, i.e., a prescribed access speed, an output sound with an waveform corresponding to the stored contents is generated. When a sound signal is transferred from the CPU, the sound signal is directly outputted in the state storing the waveform data in the storage means as they are. Consequently sound signals for an artificial sound and a natural sound can be outputted by the simple program.
