Seiko Epson has released a new synthesis chip for embedded applications using Fonix text-to-speech function.
According to a press release the S1V30120 converts text-based characters into a synthetic speech signal, which is output via the integrated DAC.
It uses a message protocol based on a clock-synchronous serial interface, the chip can be easily integrated with various host devices and MCUs.
The S1V30120 supports decoding of ADPCM data, which means that mixtures of pre-recorded speech and synthetic speech can combined.
The chip is being built for systems that require voice guidance such as those embedded in home appliances, buildings and office/industrial equipment.
