Epson ICs S1V30120 Speech Synthesis IC

Epson S1V30120 Speech Synthesis IC is a cost effective solution for adding Text-To-Speech (TTS) and ADPCM speech processing applications to portable devices. The S1V30120 contains all the required analog codecs, memory, and EPSON-supplied embedded algorithms. All applications for the Epson S1V30120 Speech Synthesis IC are controlled over a single serial interface (SPI). This allows control from a wide range of hosts and rapid integration into existing products.
