Voice synthesis IC product corresponding to several languages that can be voice conversions.

Seiko Epson Corporation ("Epson") today announced it has developed a new synthesis chip for embedded applications featuring Fonix text-to-speech (TTS). The S1V30120 is a companion chip that converts text-based characters into a synthetic speech signal, which is output via the integrated D/A converter. Since it uses a message protocol based on a clock-synchronous serial interface, the chip can be easily integrated with a wide range of host devices and microcontrollers.

The S1V30120 also supports decoding of ADPCM data, which allows mixtures of pre-recorded speech and synthetic speech to be combined as required. (For example, fixed phrases could be implemented using pre-recorded signals, while variable phrases would be synthesized.)

Target applications include a wide range of systems that require voice guidance such as those embedded in home appliances, buildings, and office/industrial equipment.
