Seiko Epson Corp. has developed the S1V3033x series of voice guidance audio decode chip for embedded applications.

The S1V3033x series supports high-quality voice codec and high-accuracy DAC, offering natural-sounding voice guidance solutions by using the dedicated voice data creation tool, which is scheduled for simultaneous release and is specially designed for this series.

Each product in the S1V3033x series is controlled by control commands from the host. Voice data stored in the built-in ROM is decoded and voice is output through the built-in high-definition 16bit DAC. The capacity of the built-in ROM can be selected from among a lineup of three models based on the application. Furthermore, as a message protocol based on a clock synchronous serial interface is employed, it is possible to easily build a system for use in combination with a wide variety of host devices or MCUs. In addition, the voice codec function of the S1V3033x series supports Epson's original voice compression format, making it possible to achieve high-quality voice guidance with a minimal amount of data.

Target applications include a wide range of systems requiring product guidance such as those embedded in home appliances, buildings and office equipment. A special tool allows users to edit voice guidance messages on a PC, doing away with the bother of studio recording and making voice guidance systems easy to develop.
