Epson has developed a natural-sounding voice data creation tool for embedded applications, as well as the S1V3034x series of voice chips and the terminal compatible S1V3S344 IC chip with built-in flash memory.

The natural-sounding voice data creation tool is a comprehensive tool combining a high-quality voice synthesis function, provided by VoiceText MISAKI, a type of female, Japanese-language voice, with features that facilitate voice guidance sentence analysis as well as pronunciation, phrase editing, and ROM image creation on a single computer, improving user-friendliness and functionality.

The S1V3034x series and the S1V3S344, with built-in flash memory, offer natural-sounding voice guidance solutions through voice codec incorporating high-quality, high-compression algorithms and high-definition D/A converters, and are matched to Epson’s natural-sounding voice data creation tool. Target applications include a wide range of systems requiring product guidance such as those embedded in home appliances, buildings, and office equipment.

Each product in the S1V3034x series is operated by control commands from the host. Voice data transmitted from the built-in ROM or host is decoded and voice is output through the built-in high-quality 16-bit D/A converter. The capacity of the built-in ROM can be selected from among a line-up of three models. Furthermore, as the series is equipped with a wide variety of interfaces including clock synchronous serial interface, I2C, and UART, it is possible to easily build a system for use in combination with a wide variety of host devices or microcontrollers. In addition, the voice codec function of the S1V3034x series utilizes Epson’s voice compression format, facilitating the creation of high-quality voice guidance with a minimal amount of data.

The S1V3S344 is an IC chip for the S1V3034x series with built-in flash memory that is terminal compatible. When used in combination with Epson’s natural-sounding voice data creation tool, this chip makes it possible to conduct voice evaluation in product development boards and product packages. Furthermore, additions and alterations arising from last-minute changes and upgrades can be performed easily, boosting the efficiency of voice guidance and software development conducted by users.
