Kaiwa Vox is text-to-speech add-on board with a Japanese robotic voice.
It just needs to receive an ASCII string of Romaji Japanese to start speaking.

The speech engine recognizes text and various speech modifiers to improve prosody.

The hardware is compatible with the mikroBUSTM standard, allowing rapid prototyping and easy integration into existing projects.

The on-board class-d amplifier can drive a small 8 ohms speaker.
A led turns on when the chip is done talking and ready to proceed.
