Use with a microcontroller
The hardware is compatible with the mikroBUSTM standard, allowing rapid prototyping and easy integration into existing projects.
The onboard class-d amplifier can drive a small 8 ohms speaker.
This vox board was designed to be used with EMY and its appropriate firmware. (in this case, the audio signal is forwarded via the “PWM” pin – the jack is not used with Emy)
It can also be used in robots, toys, or any other retrocomputing speaking devices you may think of.
Thanks to the popular mikroBUS™, this board can be instantly connected to multiple different platforms like the Arduino, the STMT32 of the Clicker2.
The onboard amplifier is quite powerful and is just waiting for the speaker to be plugged in!

Text to Speech
The chip can string phonemes to produce quite realistic speech (although with a French accent). It can also sustain notes for a nice singing effect. Here is how the Arduino code looks like :
dire("/bonj+w_r");
delay(400);
dire("&l&kt€Ronik miwzik");
delay(400);
dire("i$ b+i-n ka+I+n -ma/$=+_ine");
delay(400);
dire("+?je pE ossi murmur*?");
delay(400);
dire("je suis un arduino qui parle"); // à corriger ;-)
delay(400);You will find more information about the various phonemes and the prosodic markers in the following manual.
