Speech & Audio
Feature 1. No need for studio recording
Using Epson speech & audio LSIs for your products featuring voice guidance functions means there's no need to arrange recording studios or hire professional voice performers. This allows you to significantly reduce the product development costs and time to market. The TTS tool available from Epson makes it easy to create or modify your speech phrases. Japanese, English, and Korean language versions are now available.
Feature 2. Excellent sound quality for messages up to 4 times longer

Epson's highly efficient encoding format allows for longer phrases with excellent sound quality. The integrated high-quality 16-bit DAC produces a "silky voice" that can be coupled with high quality sound effects.
Feature 3. Easy to integrate
Epson's voice guidance LSIs use a message protocol based on asynchronous serial interface. This means they are easily integrated into a wide range of host devices and microcontrollers, reducing development time and costs, and helping achieve faster time to market.
Feature 4. Easy Development by S1V3G340 + EPSON Speech Tool
The combination of the All in One PC tool "Silky Voice" generator, and use of external SPI-Flash with the S1V3G340 makes it easy to create, write and evaluate voice data. The created voice ROM data can be written to SPI-Flash from a Host CPU via the S1V3G340. The use of high-quality audio and a high-compression format also enables the loading of large voice data capacity.
