ADPCM SPEECH SYNTHESIZER LSIs

The µPD7759 is an external ROM type speech synthesis LSI employing the waveform coding method. In addition to the ROM capability of up to 1 Mbit, the µPD7759 realizes the synthesis of speech sounds of any length by using the ADPCM data transferred from an external ROM.\nAs the synthesizing method, i ● Synthesizing method : ADPCM, PCM + waveform element methods used together\n● Sampling frequency : 5, 6 or 8 kHz\n● Bit rate (speech) : 20 to 32 K bps\n● Number of Messages : 256 (MAX.)\n● External speech data ROM ;
