Emy, the Extensible Modular Yabbler

Emy is a versatile speech synthesizer that can host a hardware synthesizer on its back via the use of a mikroBUS port. This will allow transforming Emy in a matter of a minute. (See add-on voxes)

Emy is flashed with software that emulates the famous TMS5220/TMS5100 speech chips.

Every aspect of the speech engine can be tweaked to alter the sound.

LPC data are read from the SD card so an infinite vocabulary can be loaded
Sound and vocabulary can be produced by concatenating allophones and prosody markers from the text file to affect rate, duration, and pitch. No limits here!
The OLED crisp display allows browsing amongst the files and the lines within files to pick the sound the user wants to generate.
Speech rendering can be tweaked in real-time to affect, rate, stretch, bend, pitch, and energy.
All the potentiometers have CV entries attached to them
Emy produces sounds in 3 major modes: Speech, Repeat, and VCO.

In Speech mode, the speech starts with a gate signal and is completed before waiting for a new gate signal. The speech has priority.
In Repeat mode, the speech starts and stops with the gate signal going high or low. The gate has the priority and the speech repeats while the gate is high. This mode is very useful to create crazy rhythms.
In VCO mode, the LPC engine loops while the gate is high, producing steady notes.
The firmware can be updated via the onboard USB port or via the SD card.
